Wisycom RTC25 – 2 X 50W Transmitter-Combiner

Product Overview

The Wisycom RTC25 is a compact 2×50W transmitter combiner designed to feed a single antenna from two medium-power RF transmitters. A high-quality -3 dB coupler and carefully selected RF devices keep intermodulation products very low, especially when paired with Wisycom transmitters. A sharp, low-loss output low-pass filter further suppresses harmonics so your RF system stays clean and compliant.

At a Glance

• Combines 2 × 50W RF transmitters into a single antenna feed.
• Models for 300–360 MHz and 470–880 MHz bands.
• Wide internal bandwidth for multi-channel operation.
• Very low intermodulation thanks to high-grade coupler and devices.
• Low-loss output filter to minimise harmonics and out-of-band noise.
• Integrated 100 W dummy load to absorb reflected power safely.
• Input circulators for strong isolation and reduced cross-talk.
• Front-panel RF meter for forward and reflected power monitoring.

System Details

The Wisycom RTC25 combiner accepts two transmitter inputs and feeds a single antenna output through a precision coupler, circulators and a low-pass filter network. Any reflected power from antenna mismatch is redirected into the internal 100 W dummy load so the connected transmitters stay protected. A front-panel meter provides dual scales for accurate reading in single- or dual-signal operation, with a button to check reflected power.

An SWR surveillance circuit lights a warning indicator when antenna standing-wave ratio exceeds a safe limit, giving a clear alert to cabling or antenna faults. Rugged construction and compact 1U-style mechanics make the Wisycom RTC25 well suited to fixed installations, OB vans and RF distribution racks where reliable high-performance combining is required.
