Description
The MASW-009482 is an industry leading GaAs
pHEMT MMIC single pole three throw (SP3T) switch
in a lead-free 2 mm 12-lead STQFN package with
0.5 mm lead pitch. The MASW-009482 is uniquely
configured to enable switching from a common
antenna port to CDMA Cellular, PCS, or AWS ports.
It is also ideal for other applications where a compact, high performance, symmetrical SP3T switch
is required.

Pin Configuration 3
The design is symmetric and has been fully
optimized for excellent cross modulation performance in all three paths while still maintaining excellent insertion loss and isolation. The symmetrical
design allows the user to assign CDMA Cellular,
PCS and AWS to ports RF1, RF2 or RF3 as
required to optimize the layout.

3. All package ground pins (P3,4,7,10, 12) and paddle ground
are no connection (N/C) electrically to the internal die.
M/A-COM Technology recommends connecting all ground
connections to PCB ground to ensure a good thermal path.
1. Reference Application Note M513 for reel size information.
2. All sample boards include 5 loose parts.

Cross Modulation
4. External DC blocking capacitors are required on all RF ports. Typical performance specifications are with 1000 pF blocking and decoupling
capacitors / as shown on the application schematic .
5. RX Interferer power set to –10 dBm during test to improve dynamic range of measurement system. Typical performance with –23 dBm
interferer is determined by using a linear relationship between interferer power level and cross modulation products.
