For those working on high-voltage PIN diode switching circuits, the new model MADR-010574 driver from M/A-COM Technology Solutions can be controlled by 3- or 5-V CMOS-level signals.
For those working on high-voltage PIN diode switching circuits, the new model MADR-010574 driver from M/A-COM Technology Solutions can be controlled by 3- or 5-V CMOS-level signals. It provides back bias voltage from 20 to 250 V with forward bias current to 200 mA. The driver supports series-shunt and all-series switching circuits by biasing four PIN diodes simultaneously. The MADR-010574 CMOS driver exhibits typical delay time of 8 μs when operating at its standard low quiescent current, although fast switching speed is possible at higher quiescent currents.
Typical quiescent current is 6 μA at lower voltage settings and 25 μA at 250 V. The typical bias current is 500 μA. The CMOS PIN diode driver, which is designed for operating temperatures from -40 to +125°C, is supplied in a 7-mm 16-lead QFN package and is available in tape-and-reel packaging for high-volume production.
