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

The ADMV4928 is a silicon on insulator (SOI), 37.0 GHz to 43.5 GHz, mmW 5G beamformer. The RF integrated circuit (RFIC) is highly integrated and contains 16 independent transmit and receive channels. The ADMV4928 supports eight horizontal and eight vertical polarized antennas via independent RFV and RFH input/outputs.In transmit mode, both the RFV input and RFH input signals feed into separate amplifiers. Each path after the amplifiers splits into eight independent channels via the 1:8 power splitters. In receive mode, input signals pass through either the vertical or horizontal receive channels and combine via two independent 8:1 combiners to the common RFV pin or RFH pin. In either mode, each transmit and receive channel includes a vector modulator (VM) to control the phase, and two digital variable gain amplifiers (DVGAs) to control the amplitude. The VM provides a full 360? phase adjustment range in either transmit or receive mode to provide 6 bits of resolution for 5.625? phase steps. A phase step policy for the transmit and receive VM is provided to ensure optimum phase step performance. The total DVGA dynamic range in transmit mode is 34.5, which provides 6 bits of resolution that results in 0.5 dB amplitude steps and 5 bits of resolution that results in 1 dB amplitude steps. In receive mode, the total dynamic range is 28 dB, which provides 5 bits of resolution that results in 0.5 dB amplitude steps and 5 bits of resolution that results in 1 dB amplitude steps. The DVGAs provide a flat phase response across the full gain range. A gain policy for DVGA1 and DVGA2 is provided in the AN-2074 Application Note, ADMV4928 Application Note to ensure optimized performance across the attenuation range with 0.5 dB step resolution from 0 dB to 34.5 dB attenuation for transmit mode and 0.5 dB step resolution from 0 dB to 28 dB attenuation for receive mode. The transmit channels contain individual transmit power detectors to detect either modulated or continuous wave signals to calibrate for each channel gain as well as channel to channel gain mismatch. Each receive channel contains an RF power overload circuit (receive channel overload detection circuit) to prevent potential damage to the device as a result of blocker instances. The ADMV4928 RF ports can be connected directly to a patch antenna to create a dual polarization mmW 5G subarray.The ADMV4928 can be programmed using a 3-wire or 4-wire serial port interface (SPI). An integrated, on-chip low dropout (LDO) voltage regulator generates the 1.0 V supply for the SPI circuitry to reduce the number of supply domains required. Various SPI modes are available to enable fast startup and control during normal operation. The amplitude and phase for each channel can be set individually or multiple channels can be programmed simultaneously using the on-chip memory for beamforming. The on-chip memory can store up to 2048 beam positions that can be allocated for either transmit mode or receive mode for the horizontal channels and vertical channels. On-chip nonvolatile memory (NVM) is used to store the calibrated gain and phase offset coefficients and the reference values for each individual channel from the factory. These values are used to perform channel to channel or chip to chip calibration. In addition, four address pins (CHIP_ADDx) allow independent SPI control of up to 16 devices on the same serial lines. To control multiple devices via the same serial lines with the same instructions, activate broadcast mode via the external enable pin (BR_EN). Dedicated horizontal and vertical polarization load pins (LOAD_V and LOAD_H) provide the synchronization of all devices in the same array. A horizontal and vertical polarization transmit mode and receive mode control pin (TRX_H or TRX_V) is provided for fast switching between transmit mode and receive mode.The ADMV4928 comes in a compact, 239-ball, 10 mm ? 7 mm chip scale package ball grid array (CSP_BGA). The ADMV4928 operates over the ?40?C to +95?C case temperature (TC) range. This CSP_BGA package enables the ability to heatsink the ADMV4928 from the topside of the package for the most efficient thermal heatsinking and to allow flexible antenna placement on the opposite side of the printed circuit board (PCB).APPLICATIONSmmW 5G applicationBroadband communication
