MEMS RF switches perform beyond 20GHz almost lossless
The MM5130 SP4T switch is designed to handle power levels up to 25W and demonstrates less than 0.6dB of loss at 12GHz, with 3dB performance beyond 20GHz. The MM5120 incorporates an integrated driver to facilitate switch control. This type of RF performance is usually reserved for large RF mechanical relays, which are 50x larger, 1000x slower and 1000x less reliable than products manufactured with Menlo Micro’s Ideal Switch technology, claims the company.
In addition, the MM51xx series of RF switches features extreme linearity and harmonic performance, in many cases +30dB to +40dB better than solid-state, all with high power handling capability and stable performance over much broader bandwidths, down to DC.
These attributes make the MM51xx RF switches very attractive solutions for low-loss switched filter banks, tunable filters, step attenuators, and even beam steering antennas for a variety of radio architectures in both commercial and military communications networks. The high-channel density and low losses make them suitable for ultra-compact switch matrices for test and measurement applications.
On its roadmap, the company aims to increase the density and RF performance of its switches and address the needs of a wide variety of RF front-end architectures.
