Abstract: A low voltage, switch mode PHEMT power amplifier with a 0.1 μm gate length and a low loss, lumped element, output matching circuit is disclosed that provides high performance over a frequency range of 1.4 GHz-2.5 GHz. The amplifier makes use of monolithic circuit technology for the first stage and output transistor, and uses a printed circuit board with surface mount components for the output matching network. The power output of the power amplifier is stable over a range of 60 degrees centigrade, has high power efficiencies of 44-53% with greater than 2 watts output power over the frequency range of 1.4 GHz and 2.5 GHz. In addition, through drain voltage control, the output power can be varied over a wide range between about 0.8 to 2.5 watts while still maintaining a high efficiency in the range of 50±3%.

Abstract: An ultra-wideband radio frequency (RF) apparatus for combining and/or dividing RF signals. RF apparatus includes a circuit board, a communication cable that operably engages with the circuit board, at least two transmission lines that are formed on the circuit board and operably engages with the communication cable, and at least two connectors that operably engages with the at least two transmission lines. The RF apparatus is operable in a first configuration and a second configuration. When the RF apparatus is provided in the first configuration, the RF apparatus is operable to divide a first RF signal into at least two RF signals. When the RF apparatus is provided in the second configuration, the RF apparatus is operable to combine the at least two RF signals into a second RF signal. The RF apparatus is capable of achieving a low insertion loss less than 1 dB over a bandwidth greater than 20:1.
