This mini line amplifier is a one input and one output that boosts GPS signals with up 20 dB gain. This active line amplifier accepts all major signals covering all major GNSS constellations with excellent gain flatness and low L1 noise figure. In the standard configuration, port J1 accepts DC voltage from a connected GPS receiver. This voltage is regulated and used to power the internal amplifiers while unregulated voltage is passed through the antenna port to power a connected active antenna or other upstream devices.
This network mini line amplifier (Alternate Part# MLA20 RDCBB) has BNC connectors.
- Compact & lightweight form factor
