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

The ADL8109 is a 1 GHz to 20 GHz low noise amplifier (LNA) with 36.5 dBm RF input power survivability. The ADL8109 has a gain of 15 dB, an ouptut power for 1 dB compression (OP1dB) of 16 dBm, a typical output third-order intercept (OIP3) of 28 dBm, and a noise figure of 3 dB from 8 GHz to 18 GHz. This LNA operates on a 5 V supply voltage (VDD) and has a nominal quiescent current (IDQ) of 110 mA. The ADL8109 also features an RF input and output that are internally matched to 50 Ω.

The device is housed in a RoHS-compliant, 2 mm × 2 mm, 8-lead lead frame chip scale package [LFCSP] and is specified for operation from −55°C to +125°C.
