Description

M/A-COM’s SW-461 is a multi-chip module containing six
SP4T GaAs switches, each with a driver/decoder and four
GaAs 6-way power dividers. The SW-461 utilizes Plastic Ball
Grid Array (PBGA) interconnect technology to achieve high
circuit density and superior high frequency performance. This
device is ideal for telephony applications in the AMPS
frequency bands.

The SW-461 is constructed with a multi layer PCB using a ball
grid array for the I/O connects. The combination of several
state-of-the-art technologies achieves high performance at a low
cost.
