Description

The CMX90G301 is a low-power 50 Ω cascadable

MMIC gain block suitable for a wide variety of

wireless applications operating in the 1.4 –

7.1 GHz frequency range.

The gain block has a positive gain-slope of +1dB

across the band, eliminating the need for

equalisation and compensates for increasing

system losses with frequency.

CMX90G301 is highly integrated for ease of use,

minimising component count and board area. RF

ports are matched on-chip to 50 Ω with DCblocking

capacitors. An active bias circuit allows

the device to operate over a wide supply voltage

of 2.7V to 5V with typical current of 22 mA.

Using GaAs pHEMT to provide a combination of

low DC power, low noise and high gain.

An alternative part, CMX90G302, is available for

applications that require more gain-slope compensation.
