GENERAL DESCRIPTION

The ADL7078 is a 1 GHz to 20 GHz low noise amplifier (LNA) with

32 dBm RF input power survivability. AC-coupling capacitors and

bias inductors are integrated, facilitating a compact printed circuit

board (PCB) footprint.

The ADL7078 has a gain of 13 dB, an output power for 1 dB

compression (OP1dB) of 16.5 dBm, a typical output third-order

intercept (OIP3) of 28 dBm, and a noise figure of 4.4 dB from 2

GHz to 18 GHz. This LNA operates on a 5 V supply voltage (VDD)

and has a nominal quiescent current (IDQ) of 175 mA.

The ADL7078 is fabricated on a gallium arsenide (GaAs), pseu-

domorphic high electron mobility transfer (pHEMT) process. This

device is housed in a RoHS-compliant, 24-lead, 4.00 mm × 4.00

mm, lead frame chip scale package [LFCSP] and is specified for

operation from −40°C to +85°C.
