SGA-4463 Datasheet, PDF (1/5 Pages) List of Unclassifed Manufacturers – DC-3500 MHZ CASCADABLE SIGE HBT MMIC AMPLIFIER

Product Description
Sirenza Microdevices’ SGA-4463 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 45mA , the SGA-
4463 typically provides +27 dBm output IP3, 19 dB of gain, and
+14 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.
