High-performance ultra-wideband switches and amplifiers

Latest from Custom MMIC is a new range of new high-performance microwave amplifiers and switches with ultra-wideband operation. New DC-18 GHz SP3T and SP5T non-reflective switches - Featuring a non-reflective design, the SP3T CMD234C4 provides high isolation of 40dB at 10GHz and very low insertion loss of 2dB. The CMD234C4 includes an on board binary decoder circuit, requiring only two complimentary control voltage logic lines of 0/-5V. The SP5T CMD235C4, similar to the SP3T design, features a low power integrated 3:8 TTL decoder for enhanced digital control. The CMD235C4 provides an insertion loss of 2.5dB and a high isolation of 40 dB at 10 GHz. Both the CMD235C4 and CMD234C4 come in small size and Pb-free RoHs compliant 4x4 SMT QFN packages, and have a switching speed of only 66ns. The GaAs switches are well suited to test and measurement, defence and telecommunications applications. New DC-22 GHz and 2-22 GHz Distributed Amplifiers - Offering ultra-wideband performance from DC to 22GHz, the CMD240 is a GaAs MMIC amplifier with a noise figure down to 2.2dB and a gain of 15dB. Also highly linear, the CMD240 demonstrates a 1dB compression point of 19dBm at 10 GHz and an output IP3 of 28dBm with only 80mA supply current. With slightly less current draw and a gain of 13.5dB from 2 to 22GHz, the CMD241 has a noise figure of 2.3dB. The CMD241 features enhanced linearity performance with an output P1dB of 21 dBm. Conveniently, both the CMD240 and CMD241 eliminate the need for an external DC block and are matched to 50ohm. The low-noise distributed amplifiers suit defence, aerospace, and microwave / millimetre-wave telecommunications applications. New - 26-35GHz balanced driver amplifier - In applications with very small size and high linearity requirements, the CMD243 wideband balanced driver amplifier offers 15.5dB of gain and operates from 26 to 35 GHz. The CMD243 also provides an output P1dB of 21 dBm, a low noise figure of 4.4 dB and is 50ohm matched. The CMD243 is ideal for communications, defence and space applications, says the company.
