Abstract: Radio frequency (RF) mixer circuits having a complementary frequency multiplier module that requires no balun to multiply a lower frequency base oscillator signal to a higher frequency local oscillator (LO) signal, and which has a significantly reduced IC area compared to balun-based frequency multipliers. In one embodiment, the complementary frequency multiplier module includes a complementary pair of FETs controlled by an applied base oscillator signal. The complementary FETs are coupled to a common-gate FET amplifier and alternate becoming conductive in response to the base oscillator signal. The alternating switching of the complementary FETs in response to the opposing phases of the base oscillator signal cause the common-gate FET amplifier to output a higher frequency local oscillator (LO) signal. The LO signal is coupled to the LO input of a mixer or mixer core of a type suitable for use in conjunction with a frequency multiplier.

Abstract: Various methods and circuital arrangements for biasing gates of stacked transistors of a cascode amplifier are presented, where the amplifier is configured to operate according to different modes of operation. Such circuital arrangements operate in a closed loop with a feedback voltage that is based on a sensed voltage at one or more nodes of a replica circuit of the stacked transistors, the amplifier and the replica circuit biased with same gate voltages. According to one aspect, one gate voltage is adjusted based on a comparison of the feedback voltage with a reference voltage, and other gate voltages are derived by offsetting of the one gate voltage with voltages generated by a current flow through a resistive ladder network.

Abstract: A phase shifter for altering the phase of a radio frequency signal is disclosed herein. A Lange coupler is used having reflective ports that are coupled to artificial transmission lines. The artificial transmission lines provide a reflection transmission path, the length of which can be determined by digital control lines. Transistors placed along the length of the central trace provide independent paths to ground that serve to shorten the electrical length of the ATL. Accordingly, by selectively turning the transistors on/off, the electrical length of the ATL can be selected and thus the amount of phase delay introduced by the phase shifter.

Abstract: Various methods and circuital arrangements for biasing gates of stacked transistor amplifier that includes two series connected transistor stacks of different polarities are presented, where the amplifier is configured to operate according to different modes of operation. Such circuital arrangements operate in a closed loop with a feedback error voltage that is based on a sensed voltage at a common node of the two series connected transistor stacks. According to one aspect, gate biasing voltages to input transistors of each of the two series connected stacks are adjusted by respective current mirrors that are controlled based on the feedback error voltage. According to another aspect, other gate biasing voltages are generated by maintaining a fixed gate biasing voltage between any two consecutive gate basing voltages.
