Monolithic microwave integrated circuit developer Custom MMIC of Westford, MA, USA has added to its BroadRange family of wideband gallium arsenide (GaAs) MMIC distributed amplifiers with the 2-20GHz CMD238, suitable for military, space and communications systems where small die size and high linearity are needed over a wide bandwidth.
Operating from a recommended single positive drain supply voltage of Vdd = 3-9V, at 8V (typical) and a frequency of 10GHz the device delivers 14dB of gain with a corresponding P1dB (output power at 1dB compression point) of +26dBm, an output IP3 (third-order intercept point) of +34dBm, and a 2nd-harmonic level (with Pout = 11dBm) of -33dBc. The CMD238 is a replacement for the CMM0014.
The CMD238 is a 50Ω matched design that eliminates the need for external DC blocks and RF port matching, and offers full passivation for increased reliability and moisture protection.
