RTC6701 FM/FSK Transmitter IC – Programmable 5.8GHz RF Module
The RTC6701 is a programmable FM / FSK transmitter IC built for wireless audio + video systems operating in the 5.8GHz ISM band. Single-chip RF transmit + PLL + VCO front-end — the workhorse part inside FPV video transmitters, drone telemetry links, and DIY wireless audio-video projects. Programmable frequency channels via I2C or SPI control interface let you tune across the standard 5.8GHz video band table without external bandswitch hardware.
Ideal for hobbyist + production RF designs where channel agility, low BOM count, and small footprint are critical. Pair with the matching RTC6715 receiver IC for a complete TX/RX wireless audio/video link.
Typical Use Cases
- FPV video transmitter — drone + RC car video downlink.
- Wireless audio link — wireless mic / IFB / studio applications.
- RC telemetry — bidirectional drone control + video.
- DIY RF projects — programmable 5.8GHz signal source.
