Product Description
Sirenza Microdevices聮 NGA-589 is a high performance InGaP/
GaAs HBT MMIC Amplifier. A Darlington configuration designed
with InGaP process technology provides broadband performance
up to 5.5 GHz with 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 80mA , the NGA-
589 typically provides +39 dBm output IP3, 20 dB of gain, and
+19 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.
