MMIC gain block eliminates need for equalization

It is in stock at distributor Digi-Key.

The gain block has a positive gain slope of C across the band, eliminating the need for equalization and compensating for increasing system losses with frequency.

The CMX90G301/2 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 2.7 V to 5 V with a typical current of 20 mA.

Use GaAs pHEMT to provide a combination of low DC power, low noise, and high gain.
