GENERAL DESCRIPTION

The ADL8141-CSL 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 at 14 GHz to 15

GHz, 1.4 dB at 15 GHz to 22 GHz, and 18 dBm at 15 GHz to

22 GHz, 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-CSL are

internally matched and AC-coupled.

The ADL8141-CSL is fabricated on a gallium arsenide (GaAs),

pseudomorphic high electron mobility transistor (pHEMT), monolith-

ic microwave integrated circuit (MMIC) process. The ADL8141-CSL

is housed in a RoHS-compliant, 2 mm × 2 mm, 8-lead LFCSP and

is specified for operation from −40°C to +85°C.

Additional application and technical information can be found in the

Commercial Space Products Program brochure and the ADL8141

data sheet.
