Patent number: 8648588Abstract: An RF detector configured to provide two outputs, one being a function of the true RMS power level of an RF input signal, and the other being a function of the instantaneous/peak power of the RF input signal, normalized to the average power level. The RF detector includes a variable gain detection subsystem including a single detector or detector array that provides a representation of the power level of the RF input signal. The detector or detector array is common to both the RMS power detection channel and the instantaneous/peak power detection channel of the RF detector. A method of RF detection includes providing representations of the RF input signal at different gain levels, selecting one or more of the representations, and averaging the selected signals. The gain levels of the selected representations is adjusted to provide information about the average power level of the RF input signal.Type: GrantFiled: May 17, 2011Date of Patent: February 11, 2014Assignee: Hittite Microwave CorporationInventors: Yalcin Alper Eken, Peter Katzin

Patent number: 8319560Abstract: An active bias control circuit for an amplifier includes a switch responsive to a supply voltage for providing an input current to the input of the amplifier, and a current sense circuit coupled to the switch for sensing a scaled down replica of the input current to the amplifier. A first amplifier control circuit is responsive to the current sense circuit for adjusting a first control voltage to the amplifier in response to the sensed, scaled down replica of the input current to regulate the input current to the amplifier. Circuitry for power up sequencing an amplifier for an active bias control circuit for the amplifier is also disclosed.Type: GrantFiled: October 1, 2010Date of Patent: November 27, 2012Assignee: Hittite Microwave CorporationInventors: Fatih Kocer, Yalcin Alper Eken, Abdullah Celik, Peter Katzin

Patent number: 6400227Abstract: A variable gain amplifier has at least two branches connected in parallel to drive a common output load. Each branch includes at least two FETs in a cascode configuration. A first FET in each branch is arranged to receive an input signal and to amplify the signal in a common source configuration; the second FET is arranged in a common gate configuration with its source receiving the output current of the first FET. The gate of the second FET is coupled to a corresponding gain control input so that the second FET is enabled when the gate receives an enabling gain control signal and disabled otherwise. Preferably the first and second FETs in each branch are biased in a saturation region of operation when the second FET is enabled by the gain control input. This maintains a low distortion figure throughout the dynamic range of the gain control. Preferably, the invention also includes an active fixed gain power amplification stage for coupling the output to a power amplifier.Type: GrantFiled: May 31, 2001Date of Patent: June 4, 2002Assignee: Analog Devices, Inc.Inventors: Marc Goldfarb, Rosamaria Croughwell, Peter Katzin

Patent number: 5796362Abstract: A post launch identification friend or foe fire control system for a munition has an identification and ranging interrogation unit for mounting on a munition. The interrogation unit transmits an interrogation unit which detects and verifies an incoming identification code from a remote transponder unit in reply to the interrogation code. The range of the remote transponder is determined and a decision signal is provided to the fire control circuit of the munition to enable it to avoid a friendly target; a transponder unit receives the rf carrier signal containing an incoming interrogation code from an interrogation unit on board a munition, validates the incoming interrogation code, and extracts a timing signal from it. An identification code is synchronously generated with the incoming interrogation code using the timing signal. The synchronized identification code is then transmitted back to the interrogation unit on board the munition to confirm the identification of the transponder unit and its range.Type: GrantFiled: June 13, 1994Date of Patent: August 18, 1998Assignee: Hittite Microwave CorporationInventors: Yalcin Ayasli, Peter Katzin
