Description
M/A-COM’s AT65-0009 is an integrated assembly contain-
ing two PIN diodes and a passive glass quadrature hybrid.
This device is packaged in a 5 leaded SOT plastic surface
mount package. The diodes are biased to +3.5V for maxi-
mum attenuation using the suggested Bias Circuit. The
AT65-0009 is ideally suited for GSM communication appli-
cations requiring variable attenuation in the 824 to 960
MHz bandwidth.
