    Looking for a design or chip-based ultra-low-power VHF or UHF receiver. Sensitivity should be better than -80dbm (22uV@50Ω).
    Selectivity requirements not so important.
    Power requirements should be <50uA @ 1 to 3V.
    Receiver can be powered-down for up to 250mS, and then turned on for 10mS to meet the power spec.

    This one comes close, but power is too high even if is turned on/off because wake-up time is too long.

    Any ideas?
