M/A-COM Technology Solutions (MACOM) introduced their X-Band Core Chip (MAMF-011015). According to the company, it is the industry’s first integrated core chip for the 8 GHz – 11 GHz frequency range. The device offers a unique combination of QFN surface-mount packaging with advanced MMIC design integration to provide a simple and effective solution for next generation X-Band weather radar systems.
MACOM MAMF-011015 X-Band Core Chip Features
- Frequency: 8-11 GHz
- Transmit Gain (common to TX OUT): 9 dB
- Transmit Psat: 23 dBm
- RX Gain (RX IN to common): 26 dB
- RX Input P1dB: -25 dBm
- RX NF: 1.7
- Phase Shifter Resolution (6-Bit): 5.625
- Attenuator Resolution (6-Bit): 0.5 db
The MACOM integrated MMIC features 6-bits of phase control, 6-bits of attenuation control and 26 dB of gain. The X-Band Core Chip is an easy to use serial/parallel interface in a surface mount QFN package. It is ideal for commercial radar applications and enables radar systems in early detection and warning for severe impending weather.
The MAMF-011015 is a highly integrated solution setting new standards for size, weight, and performance (SWaP). It enables the next generation of radar system design. The X-Band Core Chip integrates a CMOS logic driver with a GaAs Transmit/Receive MMIC within a single QFN package. The surface mount 7x7mm plastic package offers a cost-effective, easy to implement solution. The device’s versatility and flexibility make it ideal for weather, wildfire and related commercial radar applications.
The packaged device consists of a common leg circuit which includes digital attenuators, phase shifters, a low noise receive chain, and a transmit driver amplifier, as well as a CMOS logic driver. This integrated circuit utilizes MACOM’s advanced 0.25um PHEMT process, which has been optimized for high power and low noise amplifiers, passive and control components and allows for a high level of integration on a single MMIC.
