Cross Country Wireless HF/VHF/UHF Multicoupler
Following on from our successful SDR-4+ HF SDR Receiver we have released a HF/VHF/UHF Multicoupler.
The HF/VHF/UHF Multicoupler allows a single antenna to be shared with up to five receivers. The Multicoupler uses an ultra high IP3 InGaP HBT RF amplifier and has in-built lightning surge and over-power protection on the antenna port with over-power protection on each receiver port.
The wide frequency range allows the Multicoupler to be deployed on a variety of signals intelligence or monitoring tasks. It can be used with HF, VHF, UHF or wideband antennas as required.
A new revised design (March 2014) extends the frequency coverage to 1300 MHz.
Frequency range: 500 kHz to 1300 MHz
Input impedance: 50 ohms
Output impedance: 50 ohms
Bandwidth (-3 dB): 1 MHz to 1100 MHz
Bandwidth (-6 dB): 500 kHz to 1300 MHz
Output IP3: +40 dBm
Reverse isolation: Better than 30 dB at 1200 MHz (better than 40 dB below 100 MHz)
Receiver port isolation: Better than 20 dB at 1200 MHz (better than 30 dB below 150 MHz)
Supply voltage: 7 to 25 V
Supply current: 100 mA
Connectors: BNC female (RF in 50 ohms), BNC female (RF out 50 ohms), 2.5mm DC power socket and a M4 ground terminal.
Overall dimensions: 140 mm (L) x 90 mm (W) x 35 mm (H)
As the InGaP HBT RF amplifier used in the HF/VHF/UHF Multicoupler is a "dual-use" device i.e commercial and military under the EU Dual-Use Regulation - currently Council Regulation (EC) No 428/2009 we cannot export the Multicoupler to certain prohibited countries. We also need proof of customer identity. Payments by PayPal with a confirmed address meet the identity proof requirement.
