Custom MMIC announces the CMD241P4, a packaged version of its popular CMD241 ultra-wideband GaAs MMIC distributed low noise amplifier. The wideband operation, low noise figure, low current consumption, excellent return loss, and compact size of this distributed amplifier device make it ideal in use in L-, S-, C-, X-, Ku-, and K-band wideband radar, broadband microwave/millimeter wave communications, SATCOM, and test and measurement instrumentation applications.
The CMD241P4 exhibits gain greater than 13 dB with a low noise figure of 2.3 dB. Both the gain and noise figure of this distributed amplifier are both extremely stable over temperature, from –55 °C to +85 °C. The CMD241P4 demonstrates a 1 dB compression point beyond +21 dBm at 11 GHz and an output IP3 of +28 dBm, operating off a positive 3 to 8 volt supply, with an extremely low current draw of only 74 mA. The input return loss is typically 13 dB, and output return loss of 15 dB.

The distributed amplifier comes in a Pb-free RoHs compliant 4×4 QFN plastic package. Also incorporated into the design of this MMIC is a 50 Ohm matched impedance at the input and output ports, which removes the need for both external DC blocks and RF matching.
