Abstract

this paper presents the design of continuously tunable low noise amplifier with frequency tuning range from 2.2 to 2.8 GHz. The amplifier achieves input matching and tunability through a transformer based input matching network. The proposed circuit uses an inductively degenerated common source cascode amplifier to design the amplification stage. The circuit includes a phase shifter circuit to shift the phase of the input signal to achieve tunability through transformer. The LNA achieves a maximum gain of more than 17dB in the entire tuning range. The LNA attains a perfect impedance match across the tuning range and has a stable operation. In addition, it achieves a low noise figure ranging from 1.4dB to 5.2dB.
多波段无线电连续可调谐低噪声放大器的设计
本文设计了一种频率调谐范围为2.2 ~ 2.8 GHz的连续可调谐低噪声放大器。放大器通过基于变压器的输入匹配网络实现输入匹配和可调性。该电路采用电感退化共源级联放大器设计放大级。该电路包括移相电路,通过变压器对输入信号的相位进行移相,实现可调性。LNA在整个调谐范围内实现了超过17dB的最大增益。LNA在整个调谐范围内实现了完美的阻抗匹配,并具有稳定的运行。此外,它还实现了1.4dB至5.2dB的低噪声系数。
