Wide band receiver consist of a low NF LNA and a Mixer with high Linearity for low power applications

In the telecommunication systems, the transmitter has the task of transmitting data with relatively high power and the receiver is responsible for retrieving information from a weak signal that has been exposed to noise and interference. Therefore, the receiver should have a high gain and low number of noise (NF). As shown in Fig. 1, on the transmitter side of the blocks such as frequency synthesizer, digital to analog converter (DAC), mixer or high gain multiplier, filters and power amplifier, the receiver also includes blocks such as Low-noise amplifier, dimming mixer, analogue-to-digitalconverter (ADC) filters and converters.
