Monolithic microwave integrated circuit developer Custom MMIC of Westford, MA, USA has added two new gallium arsenide (GaAs) MMIC BroadRange distributed amplifiers to its portfolio, for applications for including military/commercial communications and instrumentation.
The DC-22GHz CMD240 and 2-22GHz CMD241 both feature a unique positive gain slope, which is said to ease 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 distributed amplifier that operates with a low noise figure, low current consumption, and high linearity in a small die size. From DC to 22GHz, the amplifier delivers over 15dB of gain with a mid-band noise figure of 2.2dB, P1dB (output power at 1dB compression point) of 19dBm and output IP3 (third-order intercept point) of 28dBm at 10GHz with a 5V supply.
The CMD241 is a wideband distributed amplifier that operates with a low mid-band noise figure of 2.3dB, an output IP3 of +28dBm, and a low supply current of 74mA in a small die size. It offers over 13dB of gain with a maximum RF input power of +20dBm.
Both amplifiers are 50Ω matched designs (eliminating the need for RF port matching) and can operate off a 3-8V power supply. The CMD241 also has on-chip blocking capacitors. Both amplifiers will be offered in QFN packages later in the summer.
