Initial version of a low cost 1800MHz power amplifier design completed and tested.

In parallel to building out the CI hardware platform we’ve been working on the design for a low cost medium power amplifier for LTE Band 3. While suitable low power RF amplifiers are available at a modest cost, as the power output increases to a watt or more, the cost starts to increase significantly. Meanwhile in rural areas of the UK it is now possible to obtain a spectrum licence under the Ofcom Shared Access scheme which permits operation with up to 42dBm EIRP. Hence an affordable power amplifier solution for those with smaller budgets would prove quite useful.
