GENERAL DESCRIPTION
The ADL8141 is a low power consumption, low noise amplifier
that operates from 14 GHz to 24 GHz. Typical gain, noise figure,
and output third-order intercept (OIP3) are 29 dB, 1.4 dB, and 18
dBm, respectively. Typical supply current is 25 mA from a 2 V
supply. OIP3 and output power for 1 dB compression (OP1dB) can
be increased by adjusting a supply-referenced resistor connected
to the RBIAS pin. The RF input and output of the ADL8141 are
internally matched and AC-coupled.
The ADL8141 is fabricated on a gallium arsenide (GaAs), pseudomorphic
high electron mobility transistor (pHEMT), monolithic
microwave integrated circuit (MMIC) process. The ADL8141 is
housed in a RoHS-compliant, 2 mm × 2 mm, 8-lead LFCSP and is
specified for operation from −40°C to +85°C.
