Description

The CMX90G302 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 +2dB

across

the

band,

eliminating

the

need

for

equalisation and compensates for increasing

system losses with frequency.

CMX90G302 is highly integrated for ease of use,

minimising component count and board area. RF

ports are matched on-

chip to 50 Ω with DC-

blocking capacitors. An active bias circuit allows

the device to operate over a wide supply voltage

of 2.7V to 5V with typical current of 20 mA.

Using GaAs pHEMT to provide a combination of

low DC power, low noise and high gain.

An alternative part, CMX90G301, is available for

applications

that

require

less

gain-slope

compensation.
