Custom MMIC of Westford, MA, USA, a developer of performance-driven monolithic microwave integrated circuits (MMICs), has added to its growing line of standard gallium nitride (GaN) products with the CMD219, a 4-9GHz low-noise amplifier (LNA) in die form.
Gain is 23dB, P1dB (output power at 1dB compression point) is +18dBm, and the noise figure is 1.1dB across its operating bandwidth. Typical bias conditions are Vdd = 10V @ 100mA and Vgg = -2.3V, although Vdd can vary from 5V to 28V. The CMD219 can also survive input power levels of up to 5W without a front-end limiter.
All ports are matched to 50 Ohm and do not require any off-chip components, apart from the bias networks which require external bypass capacitors.
Suitable applications include point-to-point and point-to-multipoint radios, military and space, and test instrumentation.
