High Survivability, Low Noise Amplifier, 1 GHz to 20 GHz

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), pseudomorphic 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.
