GENERAL DESCRIPTION

The ADL8103 is a 6 GHz to 12 GHz low noise amplifier (LNA)

with 34 dBm RF input power survivability. The ADL8103 provides a

typical gain of 25 dB at 8 GHz to 10 GHz, a 1.7 dB typical noise

figure at 8 GHz to 10 GHz, a 21 dBm typical output power for 1

dB compression (OP1dB) at 8 GHz to 10 GHz, and a typical output

third-order intercept (OIP3) of 32.1 dBm at 8 GHz to 10 GHz. This

LNA has a high output second-order intercept (OIP2) of 36.5 dBm

typical at 8 GHz to 10 GHz, making the ADL8103 suitable for mili-

tary and test instrumentation applications. The nominal quiescent

current (IDQ), which can be adjusted, is 100 mA from a 5 V supply

voltage (VDD). The ADL8103 also features inputs and outputs that

are internally matched to 50 Ω.

The device is housed in a RoHS-compliant, 2 mm × 2 mm, 8-lead

LFCSP and is specified for operation from −55°C to +125°C.
