RF Multichip Modules Target Phased-Array and Multifunction Radar Systems
Check out our coverage of IMS 2024.
Qorvo launched three highly integrated, RF multichip modules (MCMs) that can be used to build phased-array and multifunction radar systems. The modules incorporate multiple functions into a single package. The MCMs include the QPF5001 12-W X-band front-end module (FEM), the QPM2101 S-band receive variable gain amplifier (VGA), and the QPB1029 L-band filter bank (see figure).
The QPF5001 X-band FEM incorporates a power amplifier, low-noise amplifier (LNA), and limiter. Half the size of a discrete component implementation, the MCM targets the 8- to 12-GHz X-Band. The QPF5001 can interface with a circulator. Its transmit power is 12 W saturated and the receiver noise figure is 1.5 dB.
The QPM2101 S-band VGA is designed for S-Band radar applications in the 2.5- to 4.0-GHz range. The MCM includes a transmit/receive switch and a low-loss pass-through transmit path. The receive path uses a low-noise amplifier, a digital attenuator, and a driver amplifier. It supports 30 dB of small signal gain and a 1.0-dB noise figure. The VGA uses a 6-bit digital step attenuator (DSA) with 31.5-dB gain control range that can deliver 13.8 dBm of power at P1dB with 32 dBm of output TOI.
The QPB1029 L-band filter has a pair of switches on both sides of eight filters and the bypass.
