low frequency Quadplexer 25-50&66-88&135-175&350-530Mhz
ZD-QP-25-50/66-88/135-175/350-530-4NF
This is a low-frequency four-band combiner, which covers the frequency bands of 25 - 50MHz, 66 - 88MHz, 135 - 175MHz and 350 - 530MHz. It has excellent performance, with insertion loss less than 0.35dB, isolation greater than or equal to 50dB, and voltage standing wave ratio less than 1.25, which can effectively ensure the quality of signal transmission. At dual 43dBm input, the intermodulation product is as low as -153dBc, and it can withstand a maximum input power of 200W with an impedance of 50Ω. The operating temperature range is -25℃ to +65℃, the relative humidity is 5% - 95%, and it has 3kA, 10/350 μs pulse lightning protection, and the protection level reaches IP67. It uses 5PCS 4.3 - 10 female connectors, and the appearance color is gray.
