Product Description
Sirenza Microdevices NGA-486 is a high performance InGaP/
GaAs Heterojunction Bipolar Transistor MMIC Amplifier. A
Darlington configuration designed with InGaP process
technology provides broadband performance up to 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-486 typically provides +39.5 dBm output
IP3, 14.8 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.
