Disclosed is a power amplifier and a wireless transmitter. The power amplifier includes a power device and a matching network, where an output end of the power device is connected to an input end of the matching network, and the input end of the matching network includes two input ports. The power amplifier further includes a matching capacitor. The matching capacitor is connected in series to the matching network, to enable an impedance difference between the two input ports of the matching network to be within a preset range. The impedance difference between the two input ports of the matching network is enabled to be within the preset range. In this way, consistent impedances can be obtained at the two input ports of the input end of the matching network, thereby maximizing an output power of the power amplifier, and implementing true matching between the power amplifier and an antenna.

Power amplifier and wireless transmitter

The present invention discloses a millimeter-wave isolation device, comprising a first isolated circuit and a second isolated circuit and further comprising a millimeter-wave transceiver. An output end of the first isolated circuit is connected to an input end of the millimeter-wave transceiver. An output end of the millimeter-wave transceiver is connected to an input end of the second isolated circuit. The first isolated circuit and the second isolated circuit are isolated by virtue of the millimeter-wave transceiver. By adopting a short distance transmission mode with millimeter-waves taken as carrier waves, a bandwidth can reach 200 kHz to 20 GHz, and a transmission speed can reach 100 kbps to 10 Gbps. The speed is high, whereby the millimeter-wave isolation device can be applicable to any scenario. A millimeter-wave carrier wave antenna is small, and through the antenna, either wireless transmission or signal isolation can be achieved.
