Ultra-Wideband Mixer with Integrated LO Buffer Offers 23.9 dBm IIP3 in a Tiny Package

Ultra-Wideband Mixer: LTC5553

Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC5553, a double balanced mixer providing best-in-class matched bandwidth capability from 3 to 20 GHz. The mixer can be used either as an up- or downconverter. In addition, the LTC5553 delivers outstanding linearity of 23.9 dBm IIP3 at 14 GHz, and 21.5 dBm at 17 GHz. The device integrates an LO buffer requiring only 0 dBm input drive, effectively eliminating an external high power LO amplifier circuit.

Dual Output, Two-Function DC/DC µModule: LTM8049

LTM8049 Linear Technology introduces the LTM8049, a dual output, two-function DC/DC µModule® (power module) regulator in 15 mm x 9 mm x 2.42 mm BGA package. One function is SEPIC (single-ended primary-inductor converter) in which the output voltage is regulated while the input voltage can vary to be less, equal or more than the value of the output voltage.

Wideband Gain Block Amplifier: LTC6433-15

LTC6433-15Linear Technology announces the LTC6433-15, a wideband 15 dB gain block amplifier offering outstanding linearity of 47 dBm OIP3 (output third order intercept) and 3.22 dB noise figure at 150 MHz. The amplifier has excellent OP1dB (output 1dB compression point) of 19.2 dBm. The LTC6433-15 is uniquely different from other gain block amplifiers that are typically built using GaAs or pHEMT processes. These FET technologies have high 1/f noise corners on the order of 20 to 30 MHz.

Linear Tech introduces dual output boost + buck synchronous DC/DC controller

Linear Technology Corp. introduces the LTC7813, a dual output (boost + buck), low quiescent current synchronous DC/DC controller. When cascaded, its independent step-up (boost) and step-down (buck) controllers regulate the output voltage from an input voltage that can be above, below, or equal to the output voltage, including during an automotive load dump or cold crank.
