SDSX Launches the Second-Generation Silicon-Based Amplitude and Phase Multi-Function Chip
Publication time : 2024-12-06
In December 2024, SDSX successfully released the second-generation four-channel ultra-wideband beamforming TR transceiver chip SX1006-G-J, which has reached a first-class industry level in performance.
The SX1006-G-J is a four-channel (4 receive and 4 transmit) beamforming TR transceiver chip based on domestic SOI process. It covers a working frequency range of 5–18 GHz. Each channel consists of a digital-controlled phase shifter, driver amplifier, digital-controlled attenuator, switch, power combiner (divider), and other modules, supporting 6-bit phase shifting and 6-bit attenuation. The chip provides load state and transmit/receive modulation outputs. It integrates an SPI interface, digital beam control circuit, temperature sensor, over-temperature protection circuit, gain temperature compensation function, and power detection function. The transmit/receive switching time is less than 80 ns. The chip measures 4.4 mm × 6.8 mm and is powered by a single 2.5V supply. It is easy to apply, featuring radiation resistance, high integration, high precision, low power consumption, low cost, and ultra-wide bandwidth. It is suitable for applications in radar communication and other fields.
Product Highlights:
- Ultra-wide operating frequency band: 5–18 GHz;
- Low noise figure: 7–12 dB @ full band, 7–9 dB @ X-band;
- High phase shifting accuracy: 6-bit phase shifting, step size 5.625°, RMS ≤ 2°, no calibration required;
- High attenuation accuracy: 6-bit attenuation, step size 0.5 dB, RMS ≤ 0.3 dB, no calibration required;
- Transmit saturated power: 13–17 dBm @ full band, 16.5–17.5 dBm @ X-band;
- Integrated gain temperature compensation and power detection functions;
- Supports fast beam state switching with 32 beam state presets integrated.
