Embodiment

[0038] The present embodiment provides a kind of Ka wave band to transmit SOC, and its operating frequency band is 29-31GHz, it will divide into four Wilkinson power splitter W1, vector modulator (mark VM1, VM2, VM3, VM4) and power amplifier (mark PA1, PA2, PA3, PA4) are integrated in a single chip, which can support 4 channels of transmission at the same time. The chip has small area, low cost, high control precision, and great flexibility in system structure and layout. Compared with traditional digital phase-shift attenuation chips, it has many specific advantages.

[0039] The transmitting SOC specifically includes: a 1-to-4 Wilkinson power divider W1, a plurality of vector modulators (labeled VM1, VM2, VM3, VM4) connected to the 1-to-4 Wilkinson power divider W1, each vector modulator (labeled VM1 , VM2, VM3, VM4) a power amplifier (marked PA1, PA2, PA3, PA4) is also connected to the rear stage; the 1-to-4 Wilkinson power splitter W1 is used to divide the input signal int...

Abstract

The invention discloses a Ka waveband emission SOC, comprising a power divider, a plurality of vector modulators which are singly connected with the power divider, wherein the back level of each vector modulator is further connected with a power amplifier; and the power divider is used for dividing an input signal into multiple paths of output signals, each path of output signals is transmitted to the power amplifier after phase and amplitude conversion by the vector modulator, and is transmitted after being amplified by the power amplifier. The emission SOC is small in volume, high in integration degree and high in precision, and simultaneously has phase shift, amplitude conversion and signal amplification functions on the signals.

Description

technical field [0001] The invention relates to a Ka-band tile-type phased array radar signal processing device, in particular to a Ka-band transmitting SOC. Background technique [0002] Traditional phased array TR components mostly use digital phase shifters and digital attenuators for power division, phase shifting, attenuation and amplification of transmitted signals; Larger, and the accuracy is limited; especially for multi-channel situations, the phase-shift and attenuation chips increase in multiples, and the volume and complexity of the device increase. Taking a simple four-channel as an example, the phase-shift and attenuation The attenuation function needs 8 single-function chips to complete, which greatly increases the complexity of the structure and is also expensive. Therefore, there is an urgent need for a small size, high integration, high precision, and at the same time have the above-mentioned digital phase shifter and digital function of the attenuator chi...
