Description GND 4 GND 5 IN 6 Pr el im DC to 3GHz Operation Internally Matched Input and Output 22dB Small Signal Gain @2GHz P1dB = 8dBm @2GHz Single Positive Power Supply SOT363 surface-mount package 60H u u u u u u Pin Out Diagram in a Features ry The DA2709 is a general purpose, low-cost RF wideband amplifier IC. The input and output of the IC are internally matched to 50Ω 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. 3 OUT 2 GND 1 VCC Pin Descriptions Number Name Description 1 VCC 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 VCC 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 Power supply pin. An external bypass capacitor is required. Signal input pin. An external series DC blocking capacitor is required. No DC coupling allowed.
