Description
The MADR-011022 switch driver is designed to work
with MACOM’s HMIC 20 W CW SPDT PIN diode
switches. This driver has complementary outputs
which can provide up to 25 mA sinking and 20 mA
sourcing bias current to a SPDT PIN diode switch.
An all-off RF state can be achieved with the EN pin
of this driver. An extra control C2 with driver select
DS are provided to allow two drivers working
together to drive a SP3T or SP4T switch.

The back bias voltage can be selected to be any
voltage between -10 V and -25 V. This switch driver
can be easily controlled by standard TTL logic. With
low quiescent current, this driver has a typical delay
of <130 ns when driving a 100 pF capacitive load.
