Custom MMIC introduces ultra wideband devices at IMS 2016
Custom MMIC is featuring a range of new high performance microwave amplifiers and switches with ultra wideband operation at IMS 2016 in San Francisco, USA, this week.
These include DC-to-18GHz SP3T and SP5T non-reflective switches; DC-to-22GHz and 2-to-22GHz distributed amplifiers; and a 26-to-35GHz balanced driver amplifier.
Based on a non-reflective design, the SP3T CMD234C4 switch provides high isolation of 40dB at 10GHz and 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 40dB at 10GHz. Both the CMD235C4 and CMD234C4 come in small size and Pb-free RoHs compliant 4x4 SMT QFN packages, and have a switching speed of 66ns. These GaAs switches are well suited to test and measurement, military, and telecommunications applications.
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. The device demonstrates a 1dB compression point of 19dBm at 10GHz and an output IP3 of 28dBm with 80mA supply current.
With slightly less current draw and a gain of 13.5dB from 2 to 22GHz, the CMD241 amplifier has a noise figure of 2.3dB. The CMD241 features enhanced linearity performance with an output P1dB of 21dBm.
Both the CMD240 and CMD241 eliminate the need for an external DC block and are matched to 50Î©. These low-noise distributed amplifiers are suitable for military, aerospace, and microwave/millimeter wave telecommunications applications, according to the company.
In applications with very small size and high linearity requirements, the CMD243 wideband balanced driver amplifier offers 15.5 dB of gain and operates from 26 to 35GHz. The CMD243 also provides an output P1dB of 21dBm, a low noise figure of 4.4dB and is 50Î© matched. The CMD243 is suited to communications, military, and space applications.
