Differential driver doubles as versatile RF-switch driver

摘要

Designed as a high-speed driver for 12-bit ADCs, the AD8137 controls SPOT GaAs (gallium-arsenide) FET-MMIC (microwave-monolithic-IC) and PIN-diode RF switches and thus provides a low-cost and versatile alternative to conventional switch drivers. This circuit achieves typical switching speeds of approximately 7 to 11 nsec, including the propagation, delays of the driver and RF load.
