RF IC-Mixer-MS4549 - โอ๊คเซมิคอนดักเตอร์ จํากัด

Product Overview:

The MS4549 is a wideband RF mixer operating from 2 GHz to 15 GHz. It features an integrated on-chip balun on the IF port, providing a single-ended output that simplifies cascading with subsequent stages.

The device supports:

RF input range: 2–15 GHz

LO input range: 1–14 GHz

IF output range: 0.5–6 GHz

All ports exhibit ultra-wideband characteristics, enabling high flexibility across multiple system architectures.

The MS4549 integrates an on-chip LO amplifier, allowing operation with a typical LO drive of 0 dBm. It also includes an optional LO frequency doubler, enabling operation with lower LO frequencies and relaxing system LO source requirements.

The MS4549 is available in both QFN package (MS4549E) and bare die form (MS4549K), with an operating temperature range from –40°C to +125°C and excellent wideband performance.

It is ideal for applications such as microwave transceivers, wireless backhaul, point-to-point communication, phased array antennas, C/X/Ku-band radar systems, test instrumentation, and satellite modems.
