DATA SHEET • SKY73084-11 DOWNCONVERSION MIXER
Functional Description
A high isolation SPDT switch allows the SKY73084-11 to be
used for frequency hopping applications. This switch provides
greater than 60 dB of LO1 to LO2 isolation:
The SKY73084-11 is a high gain diversity mixer, optimized for
base station receiver applications. The device consists of two
diversity channels, each consisting of a low loss RF balun, high
linearity passive mixer, and a low noise IF amplifier.
LO amplifiers are also included that allow the SKY73084-11 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 for frequency hopping applications (i.e., GSM).
LO_SEL Logic:
State:
High
LO1 enabled
Low
LO2 enabled
For applications that do not require frequency hopping, LO_SEL
is fixed to one state and the appropriate LO input is used.
IF Amplifier
The SKY73084-11 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.
RF Baluns and Passive Mixer
The RF baluns provide a single ended input, which can easily be
matched to 50 Ω using a simple matching circuit. The RF
baluns offer very low loss and excellent amplitude and phase
balance.
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 250 MHz. The IF
amplifiers can be operated outside of this range, but with a
slight degradation in performance.
The high linearity mixer is a passive, double balanced mixer that
provides a very low insertion loss, and excellent 3rd Order Input
Insertion Point (IIP3) and linearity performance.
Additionally, the balanced nature of the mixer provides for
excellent port-to-port isolation.
LO Buffers and SPDT LO Switch
Electrical and Mechanical Specifications
The LO buffers allow the input power of the SKY73084-11 to be
programmed in the range of –6 to +6 dBm. The LO section has
been optimized for high-side LO injection. However, the LO can
be driven over a wide frequency range with only slight
degradation in performance.
The absolute maximum ratings of the SKY73084-11 are
provided in Table 2. The recommended operating conditions are
specified in Table 3 and electrical specifications are provided in
Table 4.
Typical performance characteristics of the SKY73084-11 are
illustrated in Figures 3 through 31.

Notes: Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value.
Nominal thermal resistance (junction to center ground pad) is 5.1 °C/W.

Evaluation Board Description
Package Dimensions
The SKY73084-11 Evaluation Board is used to test the
performance of the SKY73084-11 downconversion mixer. An
assembly drawing for the Evaluation Board is shown in Figure 32
and the layer detail is provided in Figure 33. A schematic diagram
of the SKY73084-11 Evaluation Board is shown in Figure 34.
The PCB layout footprint for the SKY73084-11 is provided in
Figure 35. Figure 36 shows the package dimensions for the
36-pin MCM and Figure 37 provides the tape and reel
dimensions.
Circuit Design Configurations
The following design considerations are general in nature and
must be followed regardless of final use or configuration:
1. Paths to ground should be made as short as possible.
2. The ground pad of the SKY73084-11 has special electrical
and thermal grounding requirements. 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 pad to dissipate the maximum wattage produced by
the circuit board.
3. Skyworks recommends including external bypass capacitors
on the VCC voltage inputs of the device.
4. Components L5, L6, L14, and L15 (see Figure 34) are high-Q
low loss inductors. These inductors must be able to pass
currents in excess of 200 mA DC.
5. Components R1 and R2 (see Figure 34) set the bias current
for the IF amplifiers. Skyworks recommends that these
resistors have a tolerance of ±1% to optimize performance
consistency of the SKY73084-11. These resistors are not
required for the Evaluation Board to operate as specified in
Tables 3 and 4.
Package and Handling Information
Since the device package is sensitive to moisture absorption, it is
baked and vacuum packed before shipping. Instructions on the
shipping container label regarding exposure to moisture after the
container seal is broken must be followed. Otherwise, problems
related to moisture absorption may occur when the part is
subjected to high temperature during solder assembly.
THE SKY73084-11 is rated to Moisture Sensitivity Level 3 (MSL3)
at 260 °C. It can be used for lead or lead-free soldering. For
additional information, refer to the Skyworks Application Note,
PCB Design & SMT Assembly/Rework Guidelines for MCM-L
Packages, document number 101752.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format. For packaging details, refer to the Skyworks
Application Note, Tape and Reel, document number 101568.
Electrostatic Discharge (ESD) Sensitivity
The SKY73084-11 is a static-sensitive electronic device. Do not
operate or store near strong electrostatic fields. Take proper ESD
precautions.

should be tented and filled with solder
mask, 30-35 μm Cu plating recommended.
Note: The cross-hatched area represents the merger of the center

pads should have at least one via connected to internal ground
planes for optimum electrical performance.
