Title:
ULTRA-WIDEBAND MICROWAVE AND MILLIMETER WAVE DIFFERENTIAL POWER AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2021/135408
Kind Code:
A1
Abstract:
Disclosed is an ultra-wideband microwave and millimeter wave differential power amplifier, comprising an input end, an output end, an input matching network connected to the input end, an output matching network connected to the output end, and an N-way power amplifier circuits connected in parallel between the input matching network and the output matching network, wherein N is the number of ways of the power amplifier circuit in the power amplifier; N≥1; each way of power amplifier circuit comprises Q differential power transistors; Q is the number of stages of the power amplifier circuit; Q≥1; two adjacent differential power transistors located on the same way are connected to each other by means of an inter-stage matching network; the differential power transistors comprise at least a pair of power transistors and gain enhancement networks in a differential working mode. This implementation enhances the anti-interference performance of the amplifier, achieves impedance matching of a large signal in an ultra-wide frequency band, greatly improves the working bandwidth of the large signal of the amplifier, and has high efficiency.
