This product is designed to combine and amplify L1 antennas with a pre-filter and supports both GPS and GLONASS signals. Featuring 3 inputs and 1 output, the number of input ports can be increased when required. Operating over the 1560–1610 MHz frequency range, it provides 24 dB gain, a maximum 7 dB noise figure, ±4 dB in-band ripple, and excellent out-of-band rejection of <70 dBc at 1500 MHz and <70 dBc at 1650 MHz. The unit offers a 2:1 VSWR, 50-ohm input/output impedance, and SMA female connectors, with a maximum RF input level of −15.5 dBm, 3.3 V DC supply, and 17 mA current consumption. Its high 1 dB input compression point, low power consumption, and superior noise performance make it suitable for demanding applications such as missile and airborne platforms. The product is also designed to withstand harsh environmental conditions.
