Ultrawideband low noise amplifier now offered in plastic 4x4 QFN package

Custom MMIC has announced 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 device exhibits gain greater than 13dB with a low noise figure of 2.3dB. Both the gain and noise figure of this distributed amplifier are both extremely stable over temperature, from -55C to +85C. The device demonstrates a 1dB compression point beyond +21dBm at 11GHz and an output IP3 of +28 dBm, operating off a positive 3 to 8 volt supply, with an extremely low current draw of only 74mA. The input return loss is typically 13dB and output return loss of 15dB. The distributed amplifier comes in a Pb-free RoHs compliant 4x4 QFN plastic package. Also incorporated into the design of this MMIC is a 50ohm matched impedance at the input and output ports, which removes the need for both external DC blocks and RF matching.
