Product Description
Sirenza Microdevices SCA-7 is a high performance Gallium
Arsenide Heterojunction Bipolar Transistor MMIC Amplifier. A
Darlington configuration is utilized for broadband performance
up to 3 GHz. The heterojunction increases breakdown
voltage and minimizes leakage current between junctions.
Cancellation of emitter junction non-linearities results in
higher suppression of intermodulation products. Typical IP3
at 40mA is +24dBm.
These unconditionally stable amplifiers provides 21dB of gain
and +12dBm of 1dB compressed power and requires only a
single positive voltage supply. Only 2 DC-blocking capaci-
tors, a bias resistor and an optional inductor are needed for
operation.
