CMX90G701QF-R705

RF Amplifiers Overview

The CMX90G701QF-R705 is a low-power, 50-ohm MMIC gain block amplifier from CML Microcircuits. It operates within the 6 GHz to 18 GHz frequency range, covering X-band and Ku-band applications. The device provides a typical gain of 10.4 dB with a positive gain slope of +1 dB across the band. Key electrical specifications include a noise figure of 2.6 dB, a 1 dB compression point (P1dB) of 10 dBm, and an output third-order intercept point (OIP3) of 20 dBm. It functions on a supply voltage between 1.8 V and 5 V with a current consumption of 22 mA. The component is housed in a compact 16-VQFN (3x3 mm) surface-mount package.

RF Amplifiers Feature Summary

• Positive gain slope characteristic (+1 dB) ensures flat response across the operational bandwidth.
• Low power consumption design suitable for battery-operated or thermally constrained systems.
• Integrated 50-ohm input and output matching eliminates external impedance networks.
• Monolithic Microwave Integrated Circuit (MMIC) construction for high reliability.

RF Amplifiers Applications

• 5G Fixed Wireless Access (FWA) infrastructure
• X-band satellite communication terminals
• Ku-band radar systems
• Point-to-point microwave links

RF Amplifiers Procurement Notes

Verify the specific suffix R705 against the manufacturer's latest datasheet to confirm reel quantity and tape specifications. Ensure compatibility with RoHS3 standards if required by the end product. Check moisture sensitivity level (MSL) ratings for proper storage and reflow soldering profiles. Confirm that the 16-VQFN footprint matches the PCB layout guidelines provided in the official documentation.

RF Amplifiers Selection Notes

Select this component when a wideband X/Ku-band solution is required with minimal power draw. The positive gain slope feature distinguishes it from flat-gain alternatives, potentially reducing equalization needs. Consider the 22 mA supply current for thermal management calculations. The 10 dBm P1dB rating defines the linear operating range for signal integrity requirements.

RF Amplifiers Part Context

This part belongs to the CMX90G series of RF amplifiers designed for wireless communications. It complements other models like the CMX90G702QF, which offers higher gain but different power characteristics. The series focuses on providing integrated solutions for modern cellular backhaul and broadband access technologies without requiring complex external biasing circuits.

RF Amplifiers Replacement Considerations

The CMX90G702QF-R705 serves as a functional alternative within the same series, offering higher gain (11.5 dB) while maintaining similar packaging and supply voltage ranges. Designers should verify if the increased gain and slight variations in noise figure and power consumption align with the system link budget before substitution.
