High performance wideband driver amplifiers with high gain and high linearity

Custom MMIC has added two new packaged driver amplifiers to their expanding product offerings, the CMD232C3 and the CMD231C3. The CMD232C3 GaAs MMIC driver amplifier functions from to 2GHz-9GHz and delivers over 15dB of temperature stable gain with an output 1 dB compression point of 17dBm, and an output IP3 of 23dBm. With this device’s high linearity in a compact 3mm x 3mm package, these amplifiers serve for defence, space and communications systems. The company eases the design process, requiring only a single 5 volt positive supply and supply current of only 90mA. The device is a 50ohm matched design to eliminate the need for external DC blocks and RF port matching. The amplifier is a replacement for the Celeritek CMM-2, now in packaged form. Offering wideband performance with a low current consumption, the CMD231C3 leverages GaAs MMIC technology to deliver over 14.5dB of temperature stable gain and have a supply current of only 45mA. These amplifiers required only a single 3V to 8V positive supply, thus simplifying the design process. It is offered in a 3mm x 3mm leadless surface mount package. Output 1dB compression point is +13.5dBm, with an output IP3 of 23.5 dBm. The device is a 50ohm matched design which eliminates the need for external DC blocks and RF port matching. The amplifier is a replacement for the Celeritek CMM-9, now in packaged form. It is ideally suited for defence, space, and communications systems where small die size and high linearity are necessary.
