Patent number: 9099975Abstract: An RF amplifier includes an input stage, a buffer stage, and an output stage. The input stage is configured to provide attenuation and impedance matching for an input radio frequency (RF) signal by providing shunt and series variable resistance current paths and RF power to RF current conversion. The input stage routes the RF current between the current paths resulting in an attenuation of the RF input current. The buffer stage is configured to provide an intermediate RF current which tracks the current level of the attenuated RF input current, thereby providing isolation between the input and output stages. The output stage is configured to provide RF current to RF power conversion, utilizing the intermediate RF current to provide an RF signal having an RF output power proportional to the RF input power.Type: GrantFiled: June 27, 2013Date of Patent: August 4, 2015Assignee: Broadcom CorporationInventor: Nir Yahav

Patent number: 8744385Abstract: A frequency conversion system includes a mixer, which is coupled to mix an input signal with a Local Oscillator (LO) signal, so as to produce an output signal. Control circuitry is configured to adjust an actual level of the LO signal provided to the mixer, so as to maintain the actual level substantially constant. A nulling signal generator is coupled to inject a nulling signal into the input signal prior to mixing with the LO signal adjusted by the control circuitry.Type: GrantFiled: September 1, 2009Date of Patent: June 3, 2014Assignee: Provigent LtdInventors: Nir Yahav, Ofer Rahmanony

Patent number: 8543072Abstract: A high accuracy programmable gain amplifier has reduced temperature dependency, reduced supply voltage dependency, and supports accurate amplifier gain and accurate amplifier gain steps. The high accuracy programmable gain amplifier allows requirements compliant electronic devices to be fabricated that are capable of providing improved operational performance with less power consumption, hence extended battery life and improved operational availability. Electronic devices that incorporate the high accuracy programmable gain amplifier described below, may experience reduced variations in operational performance resulting in a reduced need for post production calibration, reduced calibration data storage requirements, and reduced device control processor cycles for use in performing calibration operations, thereby allowing such devices to be produced at a lower cost and/or to provide users with increased operational performance and/or increased battery life and, hence, increased operational availability.Type: GrantFiled: December 23, 2011Date of Patent: September 24, 2013Assignee: Marvell International Ltd.Inventor: Nir Yahav

Patent number: 8461928Abstract: A method includes amplifying a non-constant-envelope input signal using a main amplifier having a first gain that varies depending on a supply voltage of the main amplifier. A constant-envelope signal is amplified using a reference amplifier having a second gain that varies depending on the supply voltage of the reference amplifier. Both the main amplifier and the reference amplifier are operated using a same variable supply voltage whose amplitude varies over time. A gain control signal is produced so as to compensate for changes in the second gain of the reference amplifier that are caused by the variable supply voltage. The gain control signal is applied in compensating for variations in the first gain of the main amplifier.Type: GrantFiled: January 25, 2011Date of Patent: June 11, 2013Assignee: Provigent Ltd.Inventors: Nir Yahav, Igal (Yehuda) Kushnir
