The ADL8101 from Analog Devices is a Low Noise Amplifier (LNA) that operates from 10 kHz to 22 GHz. It delivers 14 dB of gain with a noise figure of up to 3.8 dB and has a saturated output power of up to 18 dBm. This LNA has a power-added efficiency of up to 8.66% and a return loss of 10-17 dB. It is fabricated on a pseudomorphic high electron mobility transistor (pHEMT) process and has a resistor programmable bias setting.
This LNA is internally matched and has DC-coupled RF input and output pins that require external AC coupling capacitors along with a bias inductor on the RF output It requires a DC supply of 5 V and consumes less than 90 mA of current. This amplifier is available in an RoHS-compliant 8-lead LFCSP package that measures 2 x 2 x 0.85 mm and is ideal for telecommunications, instrumentation, radar, and electronic warfare applications.
