DC2554A-A-KIT

Analog Devices Inc.
The LTC4125 is a simple and high performance monolithic full bridge resonant driver capable of delivering over 5W of power wirelessly to a properly tuned receiver. The device controls the current flow in a series connected transmit coil LC network to create a simple, safe and versatile wireless power transmitter.The LTC4125 automatically adjusts its driving frequency to match the LC network resonant frequency. This AutoResonant switching allows the device to deliver maximum power from a low voltage input supply (3V to 5.5V) to a tuned receiver.

ADMV4530IQ-EVALZ

Analog Devices Inc.
The ADMV4530 is a highly integrated upconverter with an in-phase/quadrature (I/Q) mixer that is ideally suited for next generation Ka band satellite communications.An integrated low phase noise, fractional-N phase-locked loop (PLL) with a voltage controlled oscillator (VCO) and internal 2? multiplier generate the necessary on-chip local oscillator (LO) signal for the I/Q mixer, eliminating the need for external frequency synthesis. The VCO uses an internal autocalibration routine that allows the PLL to select the necessary settings and locks in approximately 100 ?s.The single-ended reference input to the PLL operates up to 500 MHz and features internal reference dividers and a multiplier for added flexibility. Additionally, the phase frequency detector (PFD) comparison frequency can be up to 250 MHz for integer mode and 160 MHz for fraction-N mode.The upconverter consists of an I/Q mixer that can operate in either I/Q mode with 500 MHz of bandwidth or in IF mode up to 3 GHz of bandwidth, which allows various radio architectures and backward compatibility with legacy systems.Immediately following the I/Q mixer are stages of gain and variable attenuation. The configuration can achieve a minimum 1 dB compression point (P1dB) compression point of 19 dBm, eliminating the need for external stages of gain.A programmable 4-wire serial port interface (SPI) allows adjustment of the quadrature phase for optimum sideband suppression. In addition, the SPI allows nulling of LO feedthrough in IF mode. In I/Q mode, the LO feedthrough can be nulled by applying external dc offset to the differential baseband I/Q inputs.An IF automatic gain control (AGC) adjusts the IF variable gain amplifier (VGA) to compensate for input power variations. During normal operation, this AGC feature can be enabled or disabled via the SPI. When disabled during normal operation, the AGC feature only works on a test tone during power-down mode to track temperature variations.The ADMV4530 upconverter comes in a RoHs compliant, 6 mm ? 6 mm, 40-terminal land grid array (LGA) package. The ADMV4530 operates over the ?40?C to +85?C case temperature range.Applications Satellite communication Point to point microwave communication
