CZE-15A 15W PLL FM Broadcast Transmitter

Product Description

The CZE-15A is a compact 15W PLL FM broadcast transmitter covering the full 88-108MHz FM band. It features dual tuning step selection (100kHz fine / 1MHz fast) for quick frequency changes, a BNC antenna connector, and both 3.5mm audio line-in and microphone inputs for flexible audio sourcing. Powered by standard 12V DC, it is suitable for mobile broadcasting, drive-in theaters, campus radio, and temporary event setups.

Featuring PLL frequency-locked loop technology, the CZE-15A delivers exceptional frequency stability of ±0ppm across a wide temperature range of -10°C to +50°C. The harmonic suppression of ≤ -60dB ensures clean transmission with minimal interference to adjacent channels.

The transmitter provides both 3.5mm audio line input and a dedicated microphone input, making it suitable for both pre-recorded content and live voice broadcasting. The BNC-type antenna connector and standard 50 Ohm impedance ensure compatibility with a wide range of FM broadcast antennas.

Powered by a standard 12V DC supply (4A minimum recommended), the CZE-15A is compact, portable, and easy to deploy. For best results, pair it with a properly tuned FM broadcast antenna — the transmission range will vary based on antenna quality, terrain, receiver sensitivity, and environmental obstructions.

Important: Never power on the transmitter without an antenna connected, as this may damage the RF output stage.
