GENERAL DESCRIPTION

The ADL8124 is a highly integrated, 1GHz to 20GHz, low noise am-

plifier (LNA). On-chip features include input and output AC coupling

capacitors, an integrated bias inductor, an integrated temperature

sensor, and an enable or disable pin (VENBL).

The typical gain and noise figure are 15dB and 2.1dB, respectively,

from 10GHz to 17GHz. The output power for 1dB compression

(OP1dB), output third-order intercept (OIP3), and output second-or-

der intercept (OIP2) are 15dBm, 29dBm, and 43dBm, respectively,

from 10GHz to 17GHz. The quiescent drain current (IDQ), which can

be adjusted, is 55mA operating from a 3.3V supply voltage (VDD).

Operation at 5V is also supported.

The ADL8124 is fabricated on a gallium arsenide (GaAs), pseudo-

morphic high electron mobility transistor (pHEMT) process. This

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

LFCSP package and is specified for operation over an extended

temperature range of −55°C to +125°C.
