The MASW-000932 is a SPDT high power,
broadband, high linearity, PIN diode T/R switch for
0.01 - 4.0 GHz applications, including WiMAX &
WiFi. The device is provided in an industry standard
lead free 4mm PQFN plastic package. This device
incorporates a PIN diode die fabricated with
MACOM's patented Silicon-Glass HMIC™ process.
This chip features two silicon pedestals embedded in
a low loss, low dispersion glass. The diodes are formed
on the top of each pedestal. The topside is fully encapsulated
with silicon nitride and has an additional polymer
passivation layer. These polymer protective coatings
prevent damage and contamination during handling
and assembly. This compact 4mm PQFN packaged SPDT switch
offers wideband 0.05 - 4.0 GHz performance with
excellent isolation to loss ratio for both TX and RX
states. The PIN diode provides 45 W C.W. power
handling at an 85°C baseplate temperature and
72 dBm IIP3 at 2010 MHz for maximum switch
performance.
