The LT5575EUF#PBF is a wideband RF demodulator (RF DEM) designed to detect and recover the information (m-ary) encoded in a Signal in a wide range of wireless standards. It is a low noise, low power, wide bandwidth device, optimized for a wide range of radio systems. Typical applications that best utilize the LT5575EUF#PBF include digital cellular, cellular radio, digital land mobile radio (LMR), point-to-point radio, digital trunked radio (DTRS), and RFID.
The LT5575EUF#PBF is configured as an AGC (automatic gain control) loop in which the RF and intermediate paths are separated by a low pass filter (LPF). By deeply separating the RF and intermediate paths, the device avoids any sort of interference between the two paths and prevents any crosstalk. As a result, the device presents a low noise and low power design.
The device integrates many components into a single demodulator, including a high performance automatic gain control (AGC) circuit and a variable gain amplifier (VGA). It also features a 10 MHz low pass filter (LPF) to block out-of-band noise and an integrated frequency and phase noise cancellation circuitry.
The LT5575EUF#PBF application field is RF demodulators, which help to detect and recover the information encoded in a signal in a wide range of wireless standards. It integrates many components for signal processing such as AGC, VGA, and LPF. It also features a phase noise cancellation circuitry which produces a low noise and low power signal even when the signal has large frequency and phase noise. This allows it to detect and recover digital signals for a wide range of radio systems such as cellular, digital land mobile radio, point-to-point radio, digital trunked radio, and RFID.
The LT5575EUF#PBF working principle is based on integrated AGC, VGA and LPF components. The AGC circuit provides adjustable gains and has a wide dynamic range for signal monitoring and tracking. The VGA provides adjustable gain to ensure proper level of operation of the demodulator, while the LPF blocks signals outside the receiver’s passband. Once input signal passes through the AGC, VGA and LPF it is demodulated and the original data is unearthed. The device also features frequency and phase noise cancellation circuitry which helps improve the signal to noise ratio and ensure a clean signal output.
