Description: | GaAs MMIC 5-BIT DIGITAL PHASE SHIFTER, 15 - 18.5 GHz |
Manufacturer: | Hittite Microwave Corporation |
Datasheet: | PDF (341K). Click here to download *) |
The HMC644 is a 5-bit digital phase shifter die which is rated from 15 to 18.5 GHz, providing 360 degrees of phase coverage, with a LSB of 11.25 degrees. The HMC644 features very low RMS phase error of 4 degrees and extremely low insertion loss variation of 0.5 dB 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. |
