Abstract
A receiver (,) provides dual band features by providing two signal paths (,) off an antenna (,), one for UHF operation (,) and one for VHF operation (,). The two signals paths (,) feed into a single broadband input (,) of a direct conversion receiver (,). The UHF path (,) utilizes UHF front end circuitry (,) while the VHF path (,) is implemented with a loading/isolator circuit (,) and a matching circuit (,). The loading/isolator circuit (,) loads the antenna (,) and isolates UHF signals while the matching circuit (,) provides a match between the loading isolator circuit (,) and the direct conversion recover (,). Selectable matching circuitry (,) and selectable VCO circuitry (,) configures the direct conversion receiver for the UHF or VHF mode of operation.
