Telewave TWR2, TWR4 Receiver Distribution Panels
The Telewave TWR2 and TWR4 Receiver Distribution Panels deliver 2 or 4 isolated 50-ohm receiver outputs from a single input, all in a compact design. The antenna port features a tuned matching network to ensure a balanced input. Each panel includes a high-gain TLA series preamplifier and a multi-voltage AC power supply, conveniently integrated into a 5.25” rack-mountable panel. Additionally, the preamplifier can be powered directly via a DC source for added flexibility.
Telewave receiver panels incorporate high-quality splitters, providing multiple balanced outputs from a single input, with 20-30 dB isolation between ports. These panels ensure reliable performance and consistent signal distribution.

Notes:
1. All unused ports should be terminated with a 50-ohm load. The
TWL-01 RF terminator is recommended for this purpose.
2. Panel gain is measured from the input port to any output port and is factory-adjusted based on specific system requirements. If not specified, the standard gain is set to 6 dB.
3. Tuning range and bandwidth depend on the frequency band and system components.
4. Exact frequencies and system gain must be provided when placing an order.
