PRELIMINARY DATA SHEET • SKY73035 DOWNCONVERSION MIXER
A high isolation SPDT switch allows the SKY73035 to be used for
frequency hopping applications. This switch provides greater than
40 dB of LO1 to LO2 isolation:
Functional Description
The SKY73035 is a high gain single mixer, optimized for base
station receiver applications. The device consists of a low loss RF
balun, high linearity passive mixer, and a low noise IF amplifier.
An LO amplifier is also included that allow the SKY73035 to
connect directly to the output of a Voltage Controlled Oscillator
(VCO). This eliminates the extra gain stages needed by most
discrete passive mixers. A Single Pole, Double Throw (SPDT)
switch has been included to select between two different LO
inputs (LO1 and LO2) for frequency hopping applications such as
GSM.
LO_SEL Input
High
LO Path Selected
LO1 (pin 11) enabled
LO2 (pin 15) enabled
Low
For applications that do not require frequency hopping, LO_SEL is
fixed to one state and the appropriate LO input is used. An internal
pull-down resistor enables the LO2 input.
RF Baluns and Passive Mixer
IF Amplifier
The RF baluns provide a single ended input, which can easily be
matched to 50 Ω using a simple external matching circuit. The RF
baluns offer very low loss, and excellent amplitude and phase
balance.
The SKY73035 includes high dynamic range IF amplifiers that
follow the passive mixers in the signal path. The outputs require a
supply voltage connection using inductive chokes. These choke
inductors should be high-Q and have the ability to handle 200 mA
or greater.
The high linearity SKY73035 is a passive, double balanced mixer
that provides a very low conversion loss, and excellent 3rd Order
Input Insertion Point (IIP3).
A simple matching network allows the output ports to be matched
to a balanced 200 Ω impedance. The IF amplifiers are optimized
for IF frequencies between 50 and 500 MHz. The IF amplifiers can
be operated outside of this range, but with a slight degradation in
performance.
Addtionally, the balanced nature of the mixer provides for high
port-to-port isolation.
LO Buffers and SPDT LO Switch
The LO buffers allow the input power of the SKY73035 to be in
the range of ±3.0 dBm. The LO section is optimized for high-side
LO injection. However, each of the two LOs can be driven over a
wide frequency range with only slight degradation in
performance.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY73035 are provided in
Table 2 and the recommended operating conditions in Table 3.

pad to dissipate the maximum heat produced by the circuit
board. For more information on soldering the SKY73035, refer
to the Package and Handling Information section of this Data
Sheet.
Evaluation Board Description
The SKY73035 Evaluation Board is used to test the performance
of the SKY73035 downconversion mixer. An assembly drawing for
the Evaluation Board is shown in Figure 3 and the layer detail is
provided in Figure 4.
3. Skyworks recommends including external bypass capacitors
on the VCC voltage inputs of the device.
Circuit Design Configurations
4. Components L5 and L4 (see Figure 5) are high-Q, low loss
inductors. These inductors must be able to pass currents in
excess of 200 mA DC.
The following design considerations are general in nature and
must be followed regardless of final use or configuration:
5. Components R7 and R8 (see Figure 5) allow for external
adjustment of the IF amplifier bias points. For operation as
specified in Tables 3 and 4, these resistors are not required.
1. Paths to ground should be made as short and as low
impedance as possible.
2. The ground pad of the SKY73035 provides critical electrical
and thermal functionality. This pad is the main thermal
conduit for heat dissipation. Since the circuit board acts as
the heat sink, it must shunt as much heat as possible from
the device. Therefore, design the connection to the ground
A schematic diagram for the SKY73035 Evaluation Board is
shown in Figure 5.
