本文介绍一种工作在-40℃～+80℃之间的微波集成收—发固态源,从米波段到五公分频率的十多个部件,全都制作在陶瓷基片和铁氧体基片上。固态源既包含了接收机的本振信号,又为发射信道激励行波管的调相器提供了载波功率。其中,采用的功分振荡器则是利用晶体管的双发射极将功率分为两路非平衡输出的一次成功尝试。在注锁电路中采用注入锁定放大器提供的稳定输出对功分振荡器进行基频注锁,使固态源的频率稳定度达2×10~(-6)。
This article presents a microwave integrated receive-transmit solid-state source operating between -40 ° C and + 80 ° C. More than a dozen components, from the m-band to the five-centimeter frequency, are fabricated on ceramic substrates and ferrite substrates. The solid state source contains both the local oscillator signal of the receiver and the carrier power for the phase modulator of the transmitting channel excitation traveling wave tube. Which uses the power oscillator is the use of dual-emitter transistor will be divided into two unbalanced power output of a successful attempt. In the lock-in circuit, a stable output provided by the injection lock-in amplifier is used to perform fundamental frequency injection lock on the power divider, so that the frequency stability of the solid state source reaches 2 × 10 -6.
