RedYutou High-Frequency Power Splitter / Combiner

The RedYutou device is a two-port power divider that can function as a splitter or combiner. It operates across a broad RF range (1500–8000 MHz) with a 50 Ω impedance and a comfortable maximum power rating of 50 W. Insertion loss is stated at ≤ 5.5 dB, and a VSWR of 1:1.3 supports stable signal routing. The compact dimensions (51x34x13 mm) and light weight (34 g per unit) make it suitable for compact installations, including external antenna setups and wireless LAN enhancements. It emphasizes port isolation to minimize cross-talk between outputs, beneficial in multi-antenna configurations.

Hyuduo 2-Way RF Power Splitter / Combiner

This 2-way power divider from Hyuduo offers a versatile solution for both splitting and combining signals. It features a wide operating frequency range from DC to 2.7 GHz, low insertion loss, and good isolation between ports. The design allows input signals to be divided into two outputs with either equal or unequal power distribution, making it suitable for distributing signals to multiple devices or aggregating signals to a single channel. It is positioned for industrial and lab environments where stable performance and broad compatibility are essential.

PALPEAL 2-Way Passive Antenna Splitter / Combiner

PALPEAL’s two-way RF splitter/combiner is designed for UHF wireless microphone applications and antenna distribution. It supports bidirectional operation, allowing one RF signal to be split into two or two signals combined into one path. It also accommodates bias voltage to front-end RF amplifiers, aiding field deployments with longer cable runs. Frequency coverage spans UHF 30–970 MHz, making it compatible with common wireless microphone ecosystems and multi-antenna coverage strategies in large venues.

Comet CF-530 High-Power Duplexer / Combiner

The Comet CF-530 is a high-power two-path duplexer/combiner designed for wide-band HF and VHF uses. It handles up to 600 W PEP on both the low-band (1.3–90 MHz) and high-band (125–470 MHz), with strong isolation (≥ 45 dB) between paths to reduce cross-interference. Insertion loss remains minimal (0.2–0.3 dB across bands), preserving transmit and receive power. This unit is well-suited for amateur radio enthusiasts and mobile/base installations requiring simultaneous multi-band operation with clean TX/RX separation.

Comet CFX-514 High-Isolation Triplexer / Combiner

The Comet CFX-514 combines three device bands—HF/6 m (1.3–90 MHz), 2 m (130–200 MHz), and 70 cm (380–500 MHz)—using a single feed line. It delivers ultra-low insertion loss across bands (approximately 0.2–0.3 dB) and supports high power handling: up to 800 W PEP on the low-pass and mid-pass bands, and 500 W on the high-pass band. High isolation between bands reduces interference, making it suitable for multi-band amateur setups, field deployments, and base installations requiring efficient, multi-band coordination.

Buying Guide: Key Purchase Considerations

• Frequency Range: Choose devices that cover your target bands. Some units are broadband (DC–2.7 GHz), while others focus on HF/VHF/UHF bands. Match to your transmitter/receiver specs and antenna system.
• Power Handling: Verify the maximum input/output power (W or W PEP) to prevent damage. Higher power ratings are essential for base stations and strong transmitters.
• Isolation and VSWR: Good isolation between ports minimizes cross-talk. A low VSWR indicates stable impedance matching and reduces reflections.
• Loss and Impedance: Look for low insertion loss (in dB) and a standard 50 Ω impedance to ensure compatibility with common RF equipment.
• Type and Configuration: Decide between splitters, combiners, duplexers, and triplexers depending on whether you need one-to-two, two-to-one, or multi-band multi-path routing.
• Physical Build: For field use, consider rugged enclosures, connectors (SMA, N-type, BNC), and mounting options. Weight and size affect installation in confined spaces.
• Compatibility: Ensure connectors and cable types align with your existing setup (coax types, connector gender, and weatherproofing if outdoors).
• Application Scenario: Amateur bands, wireless microphone distribution, CATV, satellite, or Wi‑Fi extenders each have distinct requirements; choose devices with proven performance in your scenario.
