The Class-E/F Family of ZVS Switching Amplifiers [PDF]
, 2003 A new family of switching amplifiers, each member having some of the features of both class E and inverse F, is introduced. These class-E/F amplifiers have class-E features such as incorporation of the transistor parasitic capacitance into the circuit ...

A 2.7-kW, 29-MHz class-E/F/sub odd/ amplifier with a distributed active transformer [PDF]
, 2005 A Class-E/Fodd high power amplifier (PA) using the distributed active transformer (DAT) is demonstrated at 29MHz. The DAT combines the output power from four VDMOS push-pull pairs.

High Efficiency Power Amplifier Based on Envelope Elimination and Restoration Technique [PDF]
, 2010 Due to complex envelope and phase modulation employed in modern transmitters it is necessary to use power amplifiers that have high linearity. Linear power amplifiers (classes A, B and AB) are commonly used, but they suffer from low efficiency especially

Flavour-changing Higgs couplings in a class of two Higgs doublet models [PDF]
, 2015 We analyse various flavour-changing processes like $$t\rightarrow hu,hc$$t→hu,hc, $$h\rightarrow \tau e,\tau \mu $$h→τe,τμ as well as hadronic decays $$h\rightarrow bs,bd$$h→bs,bd, in the framework of a class of two Higgs doublet models where there are ...

Transformer based front-end for a low power 2.4 GHz transceiver [PDF]
, 2010 A low power transceiver architecture for the 2.4 GHz ISM band using a 1.0 V supply is presented. It employs a transformer to convert the 100 Ω antenna impedance to almost 1 kΩ and so facilitates a low power transmitter and receiver.
