Signal Jamming Power Amplifiers

Communications Band Microwave Module

The QB-617 is a Class “A” amplifier operating in a communication band of 1930 to 1990MHz to jam communication band frequencies. This addition to API’s power amplifier product line offers a minimum output power of 100 watts with a gain of 50dB, with multiple carrier inputs. Typical current draw from a nominal +28 VDC supply at rated output power is 8 A. This design offers an isolator protected output to guard against transistor failure due to infinite VSWR mismatch.

APITech has incorporated an array of control and monitoring features including amplifier enable, high temperature alarm, thermal shutdown, forward / reverse power monitoring and temperature monitoring. The entire assembly is packaged in an aluminum chassis for heat dissipation and protection from harsh environmental conditions.
