RF Subsystems

Transforming the communications industry.

Using the Ideal Switch to develop RF subsystems enables substantial performance and reliability improvements. At the same time their size and weight decrease by several orders of magnitude.

Reconfigurable Filter

MM6005 / 225-512 MHz, 7-channel

Miniaturized. Low-loss. High-linearity.

The Ideal Switch’s superior parasitics enable the creation of revolutionary new filter designs, in both switched and tunable configurations. This can have a transformational impact on software defined radios. The MM6005 is the first example of many to come.

Differential Delay Shifter

MM6105 / DC-26 GHz, 2-bit (4-state)

Miniaturized. High-speed. High RF performance.

Currently, beam steering antennas either deliver strong RF performance and power handling using large, expensive motor-driven mechanical phase shifters. Or they use small, inefficient solid-state phase shifters that cannot handle high power and deliver poor RF performance. 

We have patented a no-compromise solution: the Ideal Switch Differential Delay Shifter.

Two MM6105 DDSs replace the mechanical phase shifters and motors inside a conventional antenna (highlighted in yellow above).

High-Density Switch Matrix

Prototype

Miniaturized. High-speed. Long life.

Switch Matrices based on the Ideal Switch can deliver the losses and isolation of an EM relay matrix in the form-factor of a solid-state matrix. This can save precious space in your test systems, while providing microsecond switching speeds, extreme lifetimes and deliver substantial reductions in total cost-of-ownership.

“The MEMS switch is an ideal element for this type of application... When compared to other solid-state switch technologies, these have very low parasitics.”
