The Mini-Circuits is a MMIC (Monolithic Microwave Integrated Circuit) bidirectional 0° splitter/combiner designed for ultra-wideband operation from DC (0 Hz) to 18 GHz.
The EP2RKU+ is a specialized Dual-Output Ku-Band Low-Noise Block Downconverter (LNB), a key component in satellite reception systems optimized for Ku-band signal processing. Designed with dual independent signal output channels, it integrates high-sensitivity reception, low-noise amplification, and precise frequency downconversion capabilities. Its core role is to capture weak Ku-band microwave signals from communication satellites via a satellite dish, process them with minimal noise interference, and convert them into manageable intermediate frequency (IF) signals for simultaneous transmission to two independent satellite receiving devices.
- Specifically engineered to receive Ku-band satellite signals (typically covering the frequency range of 10.7GHz-12.75GHz, the standard band for satellite TV and data services).
- Features a high-sensitivity antenna feed interface (compatible with standard Ku-band satellite dishes) to capture weak signals after long-distance atmospheric transmission.
- Equipped with a state-of-the-art low-noise amplifier (LNA) with an ultra-low noise figure (NF), usually as low as 0.2dB-0.3dB.
- Uses a high-stability local oscillator (LO) to mix the received Ku-band signals with the LO signal, downconverting them to standard intermediate frequencies (IF) of 950MHz-2150MHz.
- The LO frequency stability typically reaches ±1ppm (parts per million) or higher, eliminating signal distortion or frequency drift.
- Features two separate F-type coaxial output interfaces for transmitting to two independent satellite receivers simultaneously.
- Supports both "same-program" reception (two devices viewing/recording the same satellite channel) and "different-program" reception (when paired with a compatible DiSEqC switch).
- High Gain: Provides a total signal gain of 55dB-65dB, compensating for signal losses during transmission.
- Anti-Interference Filtering: Built-in band-pass filters suppress out-of-band interference and harmonic signals.
- Weather-Resistant Design: Corrosion-resistant, die-cast aluminum housing with IP-rated protection (e.g., IP65) for stable outdoor operation (-40°C to +60°C).
Primary application for home use with Ku-band satellite dishes (60cm-120cm diameter), enabling two independent TV terminals to receive satellite TV signals simultaneously.
Ideal for apartments, small guesthouses, or home offices requiring limited signal distribution without additional signal splitters.
Enables watching one satellite channel while recording another by connecting to both a satellite receiver and DVR simultaneously.
Used in small businesses or remote monitoring stations requiring dual-path Ku-band data reception for redundancy and continuous data access.
- Dual-Output Efficiency: Eliminates need for external splitters, reducing signal loss and system complexity.
- Superior Signal Quality: Ultra-low noise figure and high gain ensure clear, stable reception.
- Broad Compatibility: Works with all standard Ku-band satellite dishes and DVB-S/DVB-S2/DVB-S2X compliant receivers.
- Durable Outdoor Operation: Weather-resistant housing guarantees long-term reliability in harsh conditions.
