30 kHz to 20 GHz, Ultra-Wideband, Low Noise Amplifier

The ADL8120 is an ultra-wideband low noise amplifier (LNA) that operates from 30 kHz to 20 GHz. Typical gain and noise figure are 14 dB and 1.9 dB, respectively, from 30 kHz to 14 GHz. Output power for 1 dB compression (OP1dB), output third-order intercept (OIP3), and output second-order intercept (OIP2) are 16 dBm, 29.5 dBm and 33 dBm, respectively, from 30 kHz to 14 GHz. The nominal quiescent current (IDQ), which can be adjusted, is 55 mA from a 3.3 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. In addition, the RF input is biased through an external inductor connected between the VBIAS pin and the RFIN pin.

The ADL8120 is fabricated on a pseudomorphic high electron mobility transistor (pHEMT) process. It is housed in a RoHS-compliant, 2 mm × 2 mm, 8-lead LFCSP and is specified for operation from −55°C to +125°C.
