Product Description
Sirenza Microdevices SCA-5 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 50mA is +28dBm.
These unconditionally stable amplifiers provides up to 12dB
of gain and +13.5dBm of 1dB compressed power and
requires only a single positive voltage supply. Only 2 DC-
blocking capacitors, a bias resistor and an optional inductor
are needed for operation.
