Negative voltage drivers enable fast switching
Two negative voltage drivers from Macom Technology Solutions “exceptionally fast switching speeds” and seamless compatibility with the company’s AlGaAs and heterolithic microwave integrated circuit (HMIC) PIN diodes.
The MADR-011020 and MADR-011022 drivers are available to customers today. The level of integration complements the performance of Macom’s advanced PIN diodes, says the company, 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 -20 and -50V and provides up to 50mA sinking and sourcing bias current for medium power SPDT switches. 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 4.0mm, 16-lead PQFN packaged drivers feature built-in power sequencers, eliminating the need for external power sequencing, points out Macon. They can be controlled with standard TTL logic. Achievable switching speeds range from sub-50ns (MADR-011020) to sub-80ns (MADR-011022).
The drivers can be used as building blocks where two or more drivers can be paralleled to control two to eight throw switch configurations. An all-off RF switch state can be achieved using the drivers’ enable pins.
For over 60 years, Macom’s design and applications experts have spearheaded innovation in the RF, microwave and millimeterwave domain, developing what is claimed to be the industry’s broadest portfolio of MMICs and components spanning the entire RF signal chain. Leveraging proprietary technologies, Macom’s heterogeneous semiconductor and packaging strategy ensures that each individual RF system function is fully optimised to deliver maximum performance at the appropriate cost. Macom is committed to customers with technology, expertise, cost structures and supply chains.
Macom is a provider of high performance RF control components, providing discrete PIN diodes with I-layer thickness from one to 400 microns for frequency-specific switching and power limiting applications, discrete chip capacitors and quartz chip inductors for custom bias networks/filters, drop in wideband (2.0 to 18 GHz) bias decoupling networks for use with discrete or integrated switching circuits, multi-throw switches using Macom’s HMIC or AlGaAs technologies with on-chip biasing networks, and TTL-compatible positive and negative voltage switch/PIN diode drivers with very fast switching speed. Macom offers standard band-specific control circuits, and supports customers with devices for custom designs and circuits.
