SPDT Non-Reflective Switches cover DC-18 GHz bandwidth.
February 11, 2014 -
Housed in 3 x 3 mm, RoHS-compliant SMT package, Models CMD195C3 and CMD196C3 have isolation of 40 dB or greater, and switching speed of 1.8 nS. Model CMD195C3 features insertion loss of 2.25 dB at low end of its bandwidth, which then reduces monotonically to 1.5 dB at higher frequencies. By contrast, general-purpose Model CMD196C3 has low insertion loss of 1.5 dB that increases slightly as frequency approaches upper end of operating bandwidth.

Westford, MA — Custom MMIC (www.CustomMMIC.com), a developer of performance-driven monolithic microwave integrated circuits (MMICs), is introducing two new DC-18 GHz SPDT non-reflective switches, the CMD195C3 and the CMD196C3. While both switches cover the same bandwidth and are housed in the same 3x3 mm RoHS-compliant SMT package, they differ in their insertion loss.
The CMD195C3 has an insertion loss of 2.25 dB at the low end of its bandwidth, which then reduces monotonically to 1.5 dB at the higher frequencies. The positive slope in insertion loss versus frequency allows for several of the CMD195C3s to be cascaded together without the need for additional gain equalization circuitry. By contrast, the CMD196C3 is a general purpose SPDT design with a low insertion loss of 1.5 dB that increases slightly as the frequency approaches the upper end of the operating bandwidth.
Both switches electronically terminate the isolated port, have an isolation of 40 dB or greater, and a fast switching speed time of 1.8 nS. Switching is controlled by complementary negative logic levels of 0/-5 V. Ideal applications for these innovative new switches include microwave radio and VSAT, telecom infrastructure, test instrumentation, and military end-use.
