RF Receivers

The SA605DK/01,118 is a single chip radio frequency (RF) receiver that offers excellent performance with surprisingly low cost. It combines the functions of a double-conversion superheterodyne receiver with advanced low IF selection and digital signal processing tools. The receiver is designed to operate in the broad frequency band from 1.7 to 2.2GHz, and is intended for commercial applications such as wireless data services and wireless local area networks (WLANs).

Features

The SA605DK/01,118 has an integrated RF amplifier with a linear input dynamic range of 98dBm. It also features a low noise voltage-controlled oscillator (VCO), a low-IF selection filter, and a 14-bit analogue to digital converter with a maximum sample rate of 22.5Msps. The receiver is powered by the host processor\'s 3.3V voltage supply and operates over the -40 to +85°C temperature range.

Application Field and Working Principle

The SA605DK/01,118 is primarily used in wireless communications applications, such as WiFi and LTE networks, where it is used to receive signals from base stations or other wireless nodes. The RF signals are first amplified and then filtered by the receiver\'s RF amplifier and low-IF selection filter. The filtered signal is then converted to a digital format by the A/D converter and processed using the host processor\'s algorithms. Finally, the signals are demodulated by the host processor and output to the user interface of the device. Depending on the application, the output signal can be in the form of audio, video or data.

The SA605DK/01,118 provides a compact, low-cost solution for wireless communication applications that require advanced signal processing. Its integrated features make it a reliable and cost-effective choice for a wide range of RF receiver applications.
