概要

Description

The HMC703LP4E is a high-performance, 4-bit digital step attenuator (DSA) from Analog Devices (formerly Hittite Microwave). It operates from DC to 6 GHz, offering 0.5 dB step resolution and 31.5 dB total attenuation range.
Key features:
- Low insertion loss (~1.5 dB typical at 2 GHz).
- Fast switching speed (<50 ns).
- Serial (SPI) or parallel control interface.
- 4 mm × 4 mm QFN (LP4) package.
Ideal for RF/microwave systems, including wireless infrastructure, test equipment, and phased arrays, it provides precise attenuation with minimal phase variation. The HMC703LP4E ensures high linearity (IP3 > +50 dBm) and stable performance across temperature.
For detailed specs, refer to the datasheet.
