Preliminary
Product Description
Sirenza Microdevices’ SZM-2066Z is a high linearity class AB
Heterojunction Bipolar Transistor (HBT) amplifier housed in a
low-cost surface-mountable plastic Q-FlexN multi-chip module
package. This HBT amplifier is made with InGaP on GaAs
device technology and fabricated with MOCVD for an ideal
combination of low cost and high reliability.
This product is specifically designed as a final or driver stage
for 802.16 and 802.11b/g equipment in the 2.4-2.7 GHz
bands. It can run from a 3V to 5V supply. The external output
match and bias adjustability allows load line optimization for
other applications or over narrower bands. It features an out-
put power detector, on/off power control and high RF overdrive
robustness. This product features a RoHS compliant and
Green package with matte tin finish, designated by the ‘Z’ suf-
fix.
