MAX9988ETP+T

Overview

The MAX9988ETP+T is a radio frequency buffer and splitter designed for local oscillator signal distribution. It operates within a frequency range of 1.5 GHz to 2.2 GHz, supporting DCS, PCS, and UMTS applications. The device provides an output power level between +14 dBm and +20 dBm with a variation of 1 dB across channels. It features 40 dB reverse isolation and requires a 5 V supply voltage with a typical operating current of 229 mA. Packaged in a TQFN-EP-20 surface-mount format, it functions reliably within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides precise local oscillator buffering and splitting with minimal amplitude variation
• Ensures signal integrity through high reverse isolation characteristics
• Supports multi-standard wireless communication protocols including DCS, PCS, and UMTS

Applications

• Local oscillator distribution in mobile phone base stations
• Signal routing in DCS and PCS transceiver modules
• LO buffer stages in UMTS communication systems

Procurement Notes

Verify the specific suffix designation when sourcing, as the provided data references both MAX9988ETP+ and MAX9988ETP+T variants. Confirm that the requested component matches the exact package type and operational specifications required for your design. Ensure compatibility with the intended RF frequency range and supply voltage requirements before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring balanced LO signal distribution with tight amplitude matching. Consider the 1 dB variation specification when designing multi-channel architectures. Evaluate the thermal performance within the TQFN-EP-20 package against your system's heat dissipation capabilities. Ensure the 5 V supply rail can support the specified current draw without significant voltage drop.
