MMIC Switch Drivers: Filling the need for speed

Home » MMIC Switch Drivers: Filling the need for speed

To leverage the full potential of the latest MMICs you’ll need switch drivers that are faster and can handle higher voltages. Monzite designs and builds a new line of MMIC switch drivers that are small, fast and work well with a wide range of voltages.

Our drivers are compatible with most standard MMICs and deliver military-grade performance in miniaturized forms at affordable prices. We offer three formats: QFN (Q), hermetic flat pack (C) or an open carrier substrate (S) ready for integration. Below is a partial listing our drivers.
