1420MHz tuner pcb

Design Directions:

This tuner PCB design uses the ultra-low noise linear power chip TPS7A4701. This chip supports wide voltage input, the input voltage range is from +3V to +36V. The ripple cannot be seen with an oscilloscope, and the maximum output current can reach 1A, which is sufficient for the previously designed low-noise amplifier. This design also features programmable output voltage.

This design uses R820T as the main component, the chip has built-in low-noise amplifier, mixer, automatic gain, phase-locked loop and so on. Using this chip, the radio frequency signal of 25MHz-1700MHz can be down-converted to an intermediate frequency of 3.57MHz. It is convenient to use low sample rate analog-to-digital converters to acquire RF signals.
