The K28 Building block provides a TTL compatible ON/OFF function for microwave amplifiers, ready to use in the the tiny K package. It switches a typical RF amplifier “ON” within 40-60 nanoseconds of a logic command, and, more importantly, can switch an amplifier “OFF” (for self-protection, safety, etc), within 15 nsec. The device is compatible with 3.3V or 5V CMOS logic families.
The device accepts a -5V supply and a Vgate voltage. Logic applied to the part causes it to quickly switch the output between these two voltages
, thereby switching the amplifier between operational states.
It is rated for full MIL temperature range, and can be 883 screened.
