Targeted to high-volume automotive, broadband, cellular/3G, and WiMAX/4G applications between 50 MHz and 8 GHz, the HMC713LP3E power detector is fabricated using a SiGe BiCMOS process and converts RF signals at its input to a proportional dc voltage at its output. The part delivers 54-dB dynamic range up to 2,700 MHz with ±1-dB accuracy.
At input frequencies from 3.9 to 8 GHz, dynamic ranges up to 49 dB are achievable with ±1-dB accuracy. Input return loss is better than 10 dB across the entire operating frequency range. Housed in a RoHS-compliant leadless 3 x 3-mm plastic SMT package, the HMC713LP3E operates 2.7 to 5.5-V range and consumes 17 mA. ($3.55 ea/10 — available now.)
