Re: Rf Booster
Most stuff available now are 1 Watt maximum. There are plenty of design examples. But essentially you have to ask your self first, is it going to be mounted on the tower ? or will it be indoor , and next to the AP?. If mounted by the antenna, then you need also to use DC inserter. The design is simple, it is a bi-directional amplifier with two switches (TX/RX). The TDD switch is operated automatically using RF detector, which switched the TX path, otherwise, the LNA path is always inserted, meaning the booster switch is always switched to RX, unless AP is transmitting. The LNA can by bought from Maxim, and the PA (1 Watt) can be any of RFMD, the switches can be either PIN or FETs, there are plenty of these, but the hard one is the one to handle the 1 Watt power. NEC as I recall makes one for the 2000-25000 MHz
