Functional Diagram
General Description
The HMC697LP4(E) is a low noise, high linearity Direct
Quadrature Modulator RFIC which is ideal for digital
modulation applications from 0.2 to 4.0 GHz including;
Cellular/3G, WiMAX/4G, Broadband Wireless Access
& ISM circuits. Housed in a compact 4x4 mm (LP4)
SMT QFN package, the RFIC requires minimal external
components & provides a low cost alternative to more
complicated double upconversion architectures. The
RF output port is single-ended and matched to 50
Ohms with no external components. The LO requires
-6 to +6 dBm and can be driven in either differential or
single-ended mode. This device is optimized for a +5V
supply, and offers improved carrier feedthrough and
sideband suppression characteristics.

Sideband & Carrier Feedthrough
Calibrated vs. Uncalibrated Test Results
During the Uncalibrated Sideband and Carrier Suppression tests, care is taken to ensure that the I/Q signal paths from
the Vector Signal Generator (VSG) to the Device Under Test (DUT) are equal. The “Uncalibrated, +25 °C” Sideband
and Carrier Suppression plots were measured at room temperature, while the “Uncalibrated, over Temperature”
Sideband and Carrier Suppression plots represent the worst case uncalibrated suppression levels measured at T=
-40 °C, +25 °C, and +85 °C.
The “Calibrated, + 25 °C” Sideband Suppression data was plotted after a manual adjustment of the I/Q amplitude
balance and I/Q phase offset (skew) at +25 °C, and at each LO input power level. The +25 °C adjustment settings
were held constant during tests over temperature. The “Calibrated, over Temperature” plots represent the worst case
calibrated Sideband Suppression levels at T= -40 °C, +25 °C, and +85 °C.
The “Calibrated, +25 °C” Carrier Suppression data was plotted after a manual adjustment of the Ip/In & Qp/Qn DC
offsets at +25 °C, and at each LO input power level. The +25 °C adjustment settings were held constant during tests
over temperature. The “Calibrated, over Temperature” plots represent the worst case Carrier Suppression levels
measured at T= -40 °C, +25 °C, and +85 °C.

The circuit board used in the final application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation circuit board shown is available from
