ALM-40220
2.010GHz – 2.025GHz
TD-SCDMA 10 Watt High Power SPDT Switch
Data Sheet
Description
Avago Technologies’ ALM-40220 is a high power SPDT
switch with 10W power handling capability, high linearity
performance, low insertion loss and fast switching speed
through the use of Avago Technologies’ low distortion
silicon pin diode technologies. ALM-40220 is specifically
design for TD-SCDMA wireless infrastructure application.
The ALM-40220 is reflective SPDT switches and having
flexibility converting to absorptive mode with 50ohm load
configured externally. The circuitry needs dual positive
biasing control for Tx and Rx operation.
All matching components are fully integrated within the
module which makes the ALM-40220 extremely easy to
use. The only external parts are DC supply bypass capaci-
tors and RF choke inductor (refers to figure 16, page 10).
The ALM-40220 is housed in a miniature 5.0 x 5.0 x 1.0 mm3
multiple-chips-on-board (MCOB) module package with
5 pin configuration pads.
