Phase shifter
Hittite Microwave

The HMC543 is a 4-bit digital phase shifter die which is rated from 8 to 12 GHz, providing 0 to 360° of phase coverage, with a LSB of 22.5°. The HMC543 features very low RMS phase error of 5° and extremely low insertion loss variation of ±0.8dB across all phase states. This high accuracy phase shifter is controlled with complementary logic of 0/-3V, and requires no fixed bias voltage and is internally matched to 50 Ohms with no external components. Simple external level shifting circuitry can be used to convert a positive CMOS control voltage into complementary negative control signals.
