The CGY2350UH/C1 from MACOM is a GaAs Beamforming MMIC that operates from 34 to 36 GHz. It features a 5-bit core chip and includes 2 RF ports, a 5-bit digital phase shifter, a 5-bit digital attenuator, and switches. This IC provides a phase shifting range of 348° (in 11.25° steps) and a gain setting range of 15.5 dB (in 0.5 dB steps). It is manufactured using MACOM’s 0.18 μm gate length ED02AH PHEMT technology, uses gold bonding pads and backside metallization, and is fully protected with Silicon Nitride passivation to obtain the highest level of reliability. The MMIC has been evaluated for Space applications and is on the European Preferred Parts List of the European Space Agency.
The CGY2350UH/C1 features on-chip control logic with a serial input register that minimizes the number of bonding pads and greatly simplifies the interfacing to this device. In Tx mode, it provides a gain of 3 dB and an output P1dB of more than 10 dBm while in Rx mode, it provides a gain of 4 dB with a noise figure of less than 6 dB. It requires a DC supply of 3.3 V and consumes 180 mW of power in Rx mode and 205 mW of power in Tx mode. This beamforming IC is available in a package (Known Good Die (KGD)) that measures 3000 x 4700 μm and is ideal for radar, telecommunication, and instrumentation applications.
