RF Transmitters
We have design radio data modules (and antennas) compliant to ETS-300-220 from 10mW to 500mW. Some designs have been simple implementations using off-the-shelf chips such as Atmel AT86RF211 (TRX01) and RFMD RF2516. Most however are custom designs in the VHF and UHF bands utilising higher transmit power or very tight production cost constraints.
If your product contains an off-the-shelf radio module and you manufacture more than 2500 parts per annum, you may well be able to reduce cost by having a custom radio circuit designed and integrated onto your host PCB by RadioCAD Limited. We specialise in doing just this from initial design to mass production.
