DESCRIPTION
The TRF3703 is a very low-noise direct quadrature modulator, capable of converting complex modulated signals
from baseband or IF directly up to RF. The TRF3703 is ideal for high-performance direct RF modulation from
400 MHz up to 4 GHz. The modulator is implemented as a double-balanced mixer. The RF output block consists
of a differential to single-ended converter and an RF amplifier capable of driving a single-ended 50-Ω load
without any need of external components. The TRF3703 comes in two types, TRF370333 and TRF370315. The
TRF370333 and TRF370315 devices have different common-mode voltage ratings at the I, Q baseband inputs.
The TRF370333 requires a 3.3-V common-mode voltage, and the TRF370315 requires a 1.5-V common-mode
voltage.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground terminal.

APPLICATION INFORMATION AND EVALUATION BOARD
Basic Connections
•
•
See Figure 23 for proper connection of the TRF3703 modulator.
Connect a single power supply (4.5 V–5.5 V) to pins 18 and 24. These pins should be decoupled as shown
on pins 4, 5, 6, and 7.
•
•
Connect pins 2, 5, 8, 11, 12, 14, 17, 19, 20, and 23 to GND.
Connect a single-ended LO source of desired frequency to LOP (amplitude between –5 dBm and 12 dBm).
This should be ac-coupled through a 100-pF capacitor.
•
•
•
Terminate the ac-coupled LON with 50 Ω to GND.
Connect a baseband signal to pins 21 = I, 22 = I, 10 = Q, and 9 = Q.
The differential baseband inputs should be set to the proper level, 3.3 V for the TRF370333 or 1.5 V for the
TRF370315.
•
•
RF_OUT, pin 16, can be fed to a spectrum analyzer set to the desired frequency, LO ± baseband signal.
This pin should also be ac-coupled through a 100-pF capacitor.
All NC pins can be left floating.

GSM Applications
The TRF3703 is suited for GSM applications because of its high linearity and low noise level over the entire
recommended operating range. It also has excellent EVM performance, which makes it ideal for the stringent
GSM/EDGE applications.
WCDMA Applications
The TRF3703 is also optimized for WCDMA applications where both adjacent-channel power ratio (ACPR) and
noise density are critically important. Using Texas instruments’ DAC568X series of high-performance
digital-to-analog converters as depicted in Figure 25, excellent ACPR levels were measured with one-, two-, and
four-WCDMA carriers. See Electrical Characteristics, fLO = 2140 MHz for exact ACPR values.

DEFINITION OF SPECIFICATIONS
Unadjusted Carrier Feedthrough
This specification measures the amount by which the local oscillator component is attenuated in the output
spectrum of the modulator relative to the carrier. This further assumes that the baseband inputs delivered to the
pins of the TRF3703 are perfectly matched to have the same dc offset (VCM). This includes all four baseband
inputs: I, I, Q, and Q. This is measured in dBm.
Adjusted (Optimized) Carrier Feedthrough
This differs from the unadjusted suppression number in that the baseband input dc offsets are iteratively
adjusted around their theoretical value of VCM to yield the maximum suppression of the LO component in the
output spectrum. This is measured in dBm.
Unadjusted Sideband Suppression
This specification measures the amount by which the unwanted sideband of the input signal is attenuated in the
output of the modulator, relative to the wanted sideband. This further assumes that the baseband inputs
delivered to the modulator input pins are perfectly matched in amplitude and are exactly 90° out of phase. This
is measured in dBc.
Adjusted (Optimized) Sideband Suppression
This differs from the unadjusted sideband suppression in that the baseband inputs are iteratively adjusted
around their theoretical values to maximize the amount of sideband suppression. This is measured in dBc.
Suppressions Over Temperature
This specification assumes that the user has gone though the optimization process for the suppression in
question, and set the optimal settings for the I, Q inputs. This specification then measures the suppression when
temperature conditions change after the initial calibration is done.
Figure 26 shows a simulated output and illustrates the respective definitions of various terms used in this data
sheet. The graph assumes a baseband input of 50 kHz.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
