The Taoglas KHA16.24C (Quantum) is a 2D antenna array with integrated beamformer RFICs to provide full amplitude and phase control across the 16 elements comprising the array. This active array is integrated into a multi-layer PCB that contains the RFICs and 16 antenna elements; layers provided for power optimization and thermal control, digital control, and RF feed lines, all in the footprint of 53×84 mm. The array has separate H and V-pol ports for dual linear performance. The array scans along both azimuth and elevation axes. The array is designed to operate from 26.5 to 29.5 GHz, making this ideal for 5G applications.
Designed for use in 5G millimeter-wave systems, the KHA.16 can be interfaced with a customer-supplied transceiver and baseband assemblies for home, enterprise, and in-building applications. The provided SPI programming interface allows direct access to the beamformer chipsets to control the device configuration. The antenna has up to 2 GHz impedance bandwidth, which gives upwards of 2 Gbps data rates, making it well suited for fixed and mobile broadband capacity-hungry Next Generation Networks.
The KHA16.24C features higher than 20 dB cross-pol rejection, making it less susceptible to interference from undesired signals. The antenna can be directly connected using standard 2.92 mm connectors. The KHA16 uses four Ka-Band 5G beamformer chipsets that support four Tx/Rx radiating elements each, includes all requisite beam steering controls for 5-bit phase and gain control, and operates in half-duplex fashion to enable a single antenna to support both Tx and Rx operation.
Phased arrays (static or scanned beam) can direct or modify their radiation beam by varying the relative phase and amplitude of each element (or groups of elements) in the array. The variable phase delay enables the steering of the beam. The RF signal from the radio is input into a Tx/Rx module. In the Tx/Rx module, the RF signal is divided by a 4-way RF splitter. Each splitter output is then connected to an RF path comprising a phase shifter, amplifier, and low-pass filter. A command-line interface allows the end-user to adjust beam steering angles, transmit or receive modes, adjust the amplitude and/or phase per channel in the beamformers, etc.
The KHA16.24C has 36 elements, of which 16 are active. Those 16 are dual-polarized, meaning there are two active feeds per element for 32 total active feeds. The phase and amplitude of each feed can be independently controlled. Feeds can be "turned off" by minimizing the amplitude of the desired inactive feeds. The circuitry can take it down to one element at a time for a calibration cycle, and any combination can be created.
