Negative voltage drivers for use with high-performance AlGaAs

This provides designers with layout-efficient and cost-effective solutions while eliminating the design complexities and time to market constraints imposed by discrete componentry.

The MADR-011020 enables back bias voltage selection between -20 and -50V and provides up to 50mA sinking and sourcing bias current for medium power SPDT switches, while the MADR-011022 accommodates between -10 and -25V with up to 25mA sinking bias current and 20mA sourcing for use with low power SPDT switches. These compact 4mm, 16-lead PQFN packaged drivers feature built-in power sequencers, eliminating the need for external power sequencing, and can be easily controlled with standard TTL logic. Achievable switching speeds range from sub-50ns (MADR-011020) to sub-80ns (MADR-011022).

These drivers can be used as building blocks where two or more drivers can be parallelled to control two to eight throw switch configurations. An all-off RF switch state can be achieved using the drivers’ enable pins.

“Designers count on MACOM to provide the highest-performing PIN diode switches available in the industry leveraging our proprietary AlGaAs and HMIC technologies,” said Graham Board, Senior Director of Product Marketing, MACOM. “The new drivers introduced today are worthy complements, comprising a complete solution that makes it exceptionally easy for designers to architect and evaluate their RF switch designs.”
