20 GHz distributed amp offers positive bias
Custom MMIC, (www.CustomMMIC.com), a developer of performance-driven monolithic microwave integrated circuits (MMICs), is offering a new device from their growing MMIC library of standard products. The CMD173 is a wideband GaAs MMIC distributed amplifier die for applications from DC to 20 GHz. This device delivers greater than 15 dB of gain with a corresponding output 1 dB compression point of +18 dBm, and a noise figure of 1.5 dB at 8 GHz.
The CMD173 is an all-positive bias design, thus eliminating complicated and costly sequencing circuits while also simplifying board layout. In addition, the use of on-chip tracking circuits delivers consistent performance over temperature and process variation. The CMD173 is a 50 Ohm matched design that offers full passivation for increased reliability and moisture protection. The device does require off-chip bias networks, which is typical of this amplifier topology.
The CMD173 is suitable for microwave radio and VSAT, telecom infrastructure, test instrumentation, and military and space applications.
