Product Introduction

Product Description

Single channel agile analog modulator is low cost and high stability.

Features of agile analog modulator

1. Intermediate frequency, twice conversion frequency and with saw filter, small disturb side-band.
2. MCU technique is applied to audio intermediate frequency, image high frequency and RF local oscillator, with high frequency stability and accuracy.
3. Integrated circuit is applied to outputs, and each functional circuit of the overall unit adopts SMT technology, with high security.
4. LED display frequency, using up and down button to select any preference frequency.
5. Convenient control, all frequency level adjustments are designed ahead.
6. High dependable and high dynamic powers are applied to part of the source of voltage.
7. We can make different channels according to the customer’s requests.
