MACOM Introduces New Switch Drivers

Lowell, Massachusetts – MACOM Technology Solutions Inc. (“MACOM”) announced two new negative voltage drivers designed for use with a broad range of MACOM’s AlGaAs and HMIC PIN diode switches. The new MADR-011020 and MADR-011022 drivers enable integration that complements the industry-leading performance of MACOM’s advanced PIN diodes, providing 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 -20V and -50V and provides up to 50 mA sinking and sourcing bias current for medium power SPDT switches, while the MADR-011022 accommodates between -10V and -25V with up to 25 mA sinking bias current and 20 mA 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 paralleled to control 2 to 8 throw switch configurations. An all-off RF switch state can be achieved using the drivers’ enable pins.
