A Synchronous Pulse Power Supply for Millimeter Wave Solid State Power Amplifier

Abstract

The invention discloses a synchronous pulse power supply for a millimeter wave solid-state power amplifier. The input is +8V and +28V direct current power and TTL control signal level, and the output is +8V and +28V pulse voltage signals; the synchronous pulse power supply comprises an Mos transistor driving circuit, an output edge adjusting circuit and a modulation switch circuit; the Mos transistor driving circuit generates complementary Mos transistor driving control signals, the output edge adjusting circuit can adjust the rising edge and falling edge time of the output end of the pulse power supply, the modulation switch circuit is a complementary common-source push-pull output circuit composed of a P channel MOS transistor and an N channel MOS transistor, and the pulse power supply for the millimeter wave solid-state power amplifier is an indispensable component of the millimeter wave solid-state power amplifier as a driving source.

Background technique [0002] The traditional pulse power supply adopts a single-tube design output structure such as figure 1 As shown, the source of the Mos tube Q1 is connected to the power supply VCC, and the drain is connected to the equivalent load to the ground level GND. The equivalent load includes the resistor R1, the parasitic capacitance C1 and the parasitic inductance L1. The biggest disadvantage of this structure is that if the load presents a large capacitance, the output pulse falling edge time will be extended. Millimeter-wave solid-state power amplifiers happen to be capacitive, and this structure cannot well meet the needs of millimeter-wave solid-state power amplifiers. Moreover, the traditional power supply drive control circuit is complex, the power supply is bulky, and...

Millimeter-wave solid-state power amplifiers happen to be capacitive, and this structure cannot well meet the needs of millimeter-wave solid-state power amplifiers.

Moreover, the traditional power supply drive control circuit is complex, the power supply is large in size, and often has only one channel, which is obviously not applicable to many occasions with size restrictions.
