SGA-6289 Datasheet, PDF (1/5 Pages) List of Unclassifed Manufacturers – DC-4500 MHZ CASCADABLE SIGE HBT MMIC AMPLIFIER

Product Description
Sirenza Microdevices’ SGA-6289 is a high performance SiGe
HBT MMIC Amplifier. A Darlington configuration featuring 1
micron emitters provides high F_T and excellent thermal
perfomance. The heterojunction increases breakdown voltage
and minimizes leakage current between junctions. Cancellation
of emitter junction non-linearities results in higher suppression
of intermodulation products. At 850 Mhz and 75mA , the SGA-
6289 typically provides +34.4 dBm output IP3, 13.9 dB of gain,
and +18.1 dBm of 1dB compressed power using a single positive
voltage supply. Only 2 DC-blocking capacitors, a bias resistor
and an optional RF choke are required for operation.
