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 [email protected] 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.
