Abstract
An amplifier device, such as a Doherty amplifier device, may include an extra lead and decoupling capacitor coupled to radio frequency (RF) cold points of output impedance matching circuitry of multiple amplification paths, such as a carrier path and peaking path, of the amplifier device. The extra lead and the decoupling capacitor are configured to provide low frequency resonance decoupling for the multiple amplification paths. A drain bias voltage may be provided to the drain terminals of transistors of amplifiers of the amplifier device via the extra lead. An integrated passive device (IPD) including a wire fence and one or more conductive pads may be disposed between a carrier amplifier die and a peaking amplifier. The extra lead may be coupled to the RF cold points via the IPD. The wire fence may mitigate RF interference between the carrier amplifier die and the peaking amplifier die.
