Custom MMIC has added two new distributed amplifiers to their amplifier portfolio, the DC to 22 GHz CMD240 and 2 to 22 GHz CMD241. Both new products feature a unique positive gain slope, which eases the design of broadband systems by eliminating equalizer circuits or added amplifiers to compensate for the typical negative gain slope of most amplifiers.
The CMD240 is an ultra-wideband GaAs MMIC BroadRange distributed amplifier that operates with a low noise figure, low current consumption, and high linearity in a small die size. From DC to 22 GHz, this amplifier delivers over 15 dB of gain with a mid-band noise figure of 2.2 dB, output 1 dB compression point of 19 dBm and output IP3 of 28 dBm at 10 GHz with a 5 volt supply.
The CMD241 is a wideband GaAs MMIC BroadRange distributed amplifier that operates with a low mid-band noise figure of 2.3 dB, an output IP3 of +28 dBm, a low supply current of 74mA in a small die size. It offers over 13 dB of gain with a maximum RF input power of +20 dBm.
Both amplifiers are matched to 50 ohms, eliminating the need for RF port matching and can operate off a 3 to 8 volt power supply. The CMD241 also has on-chip blocking capacitors. Applications for these amplifiers include military/commercial communications and instrumentation. Both amplifiers will be available in QFN packages later in the summer.
