Description

A kind of L-band high power amplitude limiter

Technical field

The utility model belongs to limiter technical field, and in particular to a kind of L-band high power amplitude limiter.

Background technology

L-band high power amplitude limiter has reached test standing-wave ratio for the MICROWAVE PROTECTION device of the receiving terminal of T/R components It is small, big using power and Insertion Loss is small etc. requires.To adapt to the demand of T/R component receiving terminals microwave power signal protection, use Advanced and ripe and high performance microwave switching diode, and emulation matching has been carried out to impedance.The existing high-power limit of L-band Width device switch can complete the protection to T/R component receiving terminals, and substantially meet demand.But sent out by investigation and feedback Existing, also there are many defects in existing channel controller part, this is mainly manifested in the following aspects：Standing wave is big, low by power And Insertion Loss it is big the problems such as.

The content of the invention

The purpose of this utility model is to provide the L-band high power amplitude limiter that a kind of standing wave is small and Insertion Loss is small.

It is to realize by the following technical programs that the purpose of this utility model, which is,：

A kind of L-band high power amplitude limiter, including input interface, microwave module, output interface and the power supply being sequentially connected Module, the microwave module include two electric capacity, an inductance and 3 microwave diodes, and an electric capacity and inductance in parallel are formed Filter circuit, 3 microwave diodes in parallel are connected after filter circuit, an electric capacity is connected after microwave diode, wherein, it is described Microwave diode uses MA4P604-131 microwave diodes.

Further, the input interface is connected as rf signal reception device, and rf signal reception device receives radio frequency Signal, the frequency range of radiofrequency signal is L-band, and 0.5~0.75cm of its wavelength, frequency is 40~60GHZ.

Further, the power module includes being used for the power management for converting voltages into the voltage needed for microwave module Module.

Further, the appearance and size of the limiter is 19 × 16.3 × 5mm³。

Further, standing wave≤0.8dB of the limiter, bear microwave signal power can arrive 300W and Insertion Loss≤ 0.8dB。

It is micro- that HIGH-POWERED MICROWAVES signal by 3 MA4P604-131 microwave diodes is restricted to small-power by the utility model Ripple signal output, there is the characteristics of power is big, standing wave is small and Insertion Loss is small；In addition, its appearance and size is small, has and use installation side Just the features such as.
