The ADL5390 vector multiplier consists of a matched pair of broadband variable gain amplifiers whose outputs are summed. The separate gain controls for each amplifier are linear-in-magnitude. If the two input RF signals are in quadrature, the vector multiplier can be configured as a vector modulator or as a variable attenuator/phase shifter by using the gain control pins as Cartesian variables. In this case, the output amplitude can be controlled from a maximum of +5 dB to less than -30 dB, and the phase can be shifted continuously over the entire 360? range. Since the signal paths are linear, the original modulation on the inputs is preserved. If the two signals are independent, then the vector multiplier can function as a 2:1 multiplexer or can provide fading from one channel to another.The ADL5390 operates over a wide frequency range of 20 MHz to 2400 MHz. For a maximum gain setting on one channel at 380 MHz, the ADL5390 delivers an OP1dB of 11 dBm, an OIP3 of 24 dBm, and an output noise floor of -148 dBm/Hz. The gain and phase matching between the two VGAs is better than 0.5 dB and 1?, respectively, over most of the operating range.The ADL5390 is fabricated on Analog Devices' proprietary, high performance 25 GHz SOI complementary bipolar IC process.

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 ADMV4828 comes in a compact, 304-ball, 10 mm ? 8.5 mm chip scale package ball grid array (CSP_BGA). The ADMV4828 operates over the ?40?C to +95?C case temperature (TC) range. This CSP_BGA package enables the ability to heatsink the ADMV4828 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
