This paper presents a single stage cascode pseudomorphic high electron mobility transistor (pHEMT) low noise amplifier (LNA) using a shunt feedback capacitor at 915 MHz for UHF wind profiling radar application. Capacitive shunt feedback is a solution for simultaneous noise and power match. The source degenerated inductance topology is used with the cascode transistor capacitive shunt feedback to improve stability, input and output return losses, and noise figure. Using cascode transistor capacitive shunt feedback excellent noise figure and gain (S 21 ) are obtained. Low cost and low loss dielectric substrate RT/duroid RO4003C is used in the LNA design. Simulated results of LNA show that overall gain of 25.311 dB and noise figure (NF) of 0.258 dB. Input and output return losses are less than -15 dB. To characterize linearity, third order input intercept point and third order output intercept is simulated as 50.62 dBm, 69.60 dBm respectively.Keywords -Cascode, capacitive shunt feedback, low noise amplifier, linearity, noise figure, ultra high frequency(UHF), wind profiling radar.I.

“…As for the single-ended amplifiers, bias current of this arrangement should be selected due to noise and linearity considerations. While a more detailed analysis of this topology, as presented for the inductively degenerated cascade amplifier with capacitive shunt feedback in [16], might be desirable at this point, limited space for this section does not permit a lengthy discussion. Instead, we allude to the amplifier of [17] from which the topology of Fig.…”

A monolithic integrated low noise amplifier (LNA) based on a SiGe HBT process for a global navigation satellite system (GNSS) is presented. An optimizing strategy of taking parasitic capacities at the input node into consideration is adopted and a method and design equations of monolithically designing the LC load and the output impedance matching circuit are introduced. The LNA simultaneously reaches excellent noise and input/output impedance matching. The measurement results show that the LNA gives an ultra-low noise figure of 0.97 dB, a power gain of 18.6 dB and a three-order input intermodulation point of 6 dBm at the frequency of 1.575 GHz. The chip consumes 5.4 mW from a 1.8 V source and occupies 600 650 m 2 die area.
