Custom MMIC launches LNA offering noise figure of 1.5dB at 6-18GHz

Monolithic microwave integrated circuit developer Custom MMIC of Westford, MA, USA is offering two new devices from its growing MMIC design library. The CMD157 (die) and CMD157P3 (packaged) are gallium arsenide (GaAs) MMIC low-noise amplifiers (LNAs) for applications at 6-18GHz. The broadband devices each have a low noise figure of 1.5dB, deliver greater than 25dB of flat gain, and have a corresponding output 1dB compression point (P1dB) of +10dBm.

Both the CMD157 and CMD157P3 are 50 Ohm matched designs, eliminating the need for external DC blocks and RF port matching. The CMD157 is suitable for chip-and-wire applications, whereas the CMD157P3 is housed in a leadless RoHS-compliant 3mm x 3mm plastic surface-mount package. The amplifiers are biased with a single positive voltage of +3.0V @ 52mA. RF power can be applied at any time.

Custom MMIC says that the LNAs are much smaller, lower-cost alternatives to hybrid amplifiers in this frequency range. Suited to broadband electronic warfare (EW) and communication systems, where small size and low power consumption are needed, they can also be used in low-noise down-converters, microwave radio receiver systems, and radar receivers.
