IMARK   209RF- VHF/UHF RF PCB Module

 

Compact Synthesised RF Module

Imark Stock # See listing below

Features:

  • Direct Loop PLL Synthesiser
  • Separate TX and RX VCO's
  • Wide Switching Range
  • Compact Size
  • Most frequency bands between 66 and 520 MHz
  • SMT technology for reliability
  • Meets AS4295 for fixed locations

DESCRIPTION:

The Kyodo KG209 RF PCB module is ideal for OEM RF applications such as telemetry or data transfer. This PCB module is supplied complete with PLL, VCO, AVR, FM receiver, and a 5 watt RF Power Amplifier. It only requires serial data from your micro-controller to the PLL and Audio I/O buffering to complete your product.

The KG209 RF PCB module features reliability that has been proven in thousands of installations worldwide. It has RF performance that meets base station standards, and is so compact that its volume is less than 60cm3. SMT component technology is utilised for reliability and to meet size constraints.

The module has a direct loop PLL system and can be serially programmed. A double balanced mixer is incorporated to reduce the effects of intermodulation while separate receiver and transmitter VCO's are employed to enable faster TX-RX switching. The RF PA module is capable of 5 watts RF output.
