GENERAL DESCRIPTION

The ADL8101 is an ultrawideband low noise amplifier (LNA) that

operates from 10 kHz to 22 GHz. The typical gain and noise figure

are 14 dB and 3.5 dB, respectively, from 10 kHz to 16 GHz. The

output power for 1 dB compression (OP1dB), output third-order

intercept (OIP3), and output second-order intercept (OIP2) are 15

dBm, 26 dBm, and 29 dBm, respectively, from 10 kHz to 16 GHz.

The nominal quiescent current (IDQ), which can be adjusted, is

90 mA from a 5 V supply voltage (VDD). The internally matched,

DC-coupled RF input and output pins require external AC coupling

capacitors along with a bias inductor on RFOUT.

The ADL8101 is fabricated on a pseudomorphic high electron mobi-

lity transistor (pHEMT) process. It is housed in an RoHS-compliant,

2 mm × 2 mm, 8-lead LFCSP and is specified for operation from

−55°C to +125°C.
