Guide for the MC Devices D2006TX VHF Narrow Band Transmitter covering description, parameters, wiring, and frequency configuration.
The D2006TX is a VHF narrow‑band FM transmitter module designed for wireless audio or digital transmission in the 27‑300 MHz range. It integrates a PLL, VCO, FM modulator, amplifier, and low‑pass filter, and can be configured for narrow‑band (5 kHz) or wide‑band (25 kHz) channel spacing.
The document provides a description of the module, basic parameters, pin layout, recommended operating voltages, and detailed instructions for setting reference and VCO frequencies using serial programming of the internal MCD2006G IC. It also includes configuration examples, a group‑identification code table, and an important notice on warranty and product updates.
| Output power | 12 ± 1 dBm |
|---|---|
| Supply voltage | 2.7 V‑4.5 V |
| Output impedance | 50 Ω |
| Current consumption (VDD=4.0 V) | 45 mA |
| Operating frequency range | 27‑300 MHz |
| Crystal frequency | 4 MHz |
| Audio input impedance | 600 kΩ |
| Frequency response | ±3 dB, 50 Hz‑20 kHz |
| Modulation degree | 1 kHz, 100 mV input → 4.5 kHz deviation |
The transmitter delivers an output power of 12 ± 1 dBm.
It operates from a supply voltage between 2.7 V and 4.5 V.
Frequency is set by sending serial data to the CLK, DATA, and EN pins, which program the internal MCD2006G IC.
