Description
The DA2709 is a general purpose, low-cost RF wideband amplifier IC. The input and out-
put of the IC are internally matched to 50
for convenient cascading. Applications include
IF and RF amplification in wireless voice and data communication products from DC to
3GHz. The DA2709 requires minimal external components for DC bias.

Description
1
V
CC
Power supply pin. An external bypass capacitor is required.
2
GND
Ground connection. Keep PCB traces as short as possible and connect
immediately to ground plane for best performance.
3
OUT
Signal output and bias pin. An external choke inductor L to V
CC
is required
for biasing. An external series DC blocking capacitor is also required.
4
GND
Same as pin 2.
5
GND
Same as pin 2.
6
IN
Signal input pin. An external series DC blocking capacitor is required. No
DC coupling allowed.
