SGA-3586 Datasheet, PDF (1/5 Pages) List of Unclassifed Manufacturers – DC-5000 MHz Silicon Germanium Cascadeable Gain Block

Preliminary
Product Description
Sirenza Microdevices’ SGA-3586 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 35mA , the SGA-
3586 typically provides +25 dBm output IP3, 25dB of gain,
and +13.5 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.
