Abstract

When an RF power amplifier circuit is integrated on a package, at least one bias voltage is coupled to at least one amplifier circuit on the package via two or more pins / connectors. In particular, at least one of the gate and drain bias voltages is coupled to one or more amplifier circuits via at least two pins / connectors. In some embodiments, two or more bias voltage pins / connectors are connected together on a package, placing the pins / connectors in parallel, which reduces the inductance associated with the pins / connectors. In some embodiments, at least two pins / connectors connected to the same bias voltage are disposed on either side of the RF signal pin / conductor, simplifying routing of signals on the package, providing greater flexibility of placement and routing on the package.

Description

[0001] Related applications [0002] This application claims priority to US Patent Application Serial No. 16 / 414,955, filed May 17, 2019, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates generally to RF power amplifier circuits, and more particularly to systems and methods for providing bias voltages to amplifier circuits on a package by connecting two or more pins / connectors to the same bias voltage. Background technique [0004] Modern wireless communication networks are modulated to radio frequency (RF) signals by transmitting typically between fixed access points (called base stations, eNBs, gNBs, etc.) and a large number of mobile terminals (user equipment or UEs, tablets, laptops, etc.) on the voice and data content to operate. Signal transmission in both directions requires RF power amplifiers. In both cases, efficiency (output power divided by input power) is an important consideration. Effic...
