PolyPhaser (Minden, NV) unveiled its new SXL Series of surge and lightning protection units, which deliver high-power RF protection across a wide bandwidth enabling the same units to be used for many different applications. Featuring multi-strike capability and low throughput energy, the SXL devices come in full weather-proof housings.
The SXL RF protectors provide surge capabilities in accordance with IEC 100-4-5, 8 µs/20 µs at 18 kA (minimum) (DIN 30 kA) and IEC 1000-4-5, 10 µs/350 µs at 10 kA. The frequency ranges covered are the 800 MHz to 2,300 MHz DSXL and DSXL-D, the 1,200 MHz to 2,800 MHz PSXL, the 1,700 MHz to 2,300 MHz PSXL-D, and the 1,800 MHz to 3,800 MHz and 4,200 MHz to 6,000 MHz LSXL.
Return loss for the SXL Series protectors is above 26 dB (>20 dB for the LSXL units). Insertion loss is ≤0.1 dB (0.2 dB typical for the LSXL), and RF power is 300 W for N connectorized devices (10 W LSXL) or 750 W using 7/16 DIN dc blocked connectors. Surge throughput energy is <500 µJ (6 kV/3 kA 8 µs/20 µs); peak let-through voltage is ±1 V (6 kV/3 kA 8 µs/20 µs).
