HMC643LC5_08

HMC643LC5 v01.1208 GaAs MMIC 6-BIT DIGITAL PHASE SHIFTER, 9 - 12 GHz Typical Applications The HMC643LC5 is ideal for: • EW Receivers • Weather & Military Radar • Satellite Communications • Beamforming Modules • Phase Cancellation Features Low RMS Phase Error: 4.5° Low Insertion Loss: 7 dB High Linearity: +38 dBm 360° Coverage, LSB = 5.625° 32 Lead Ceramic SMT Package: 25mm2 Functional Diagram General Description The HMC643LC5 is a 6-bit digital phase shifter which is rated from 9 to 12 GHz, providing 360 degrees of phase coverage, with a LSB of 5.625 degrees. The HMC643LC5 features very low RMS phase error of 4.5 degrees and extremely low insertion loss variation of ±0.75 dB across all phase states. This high accuracy phase shifter is controlled with complementary logic of 0/-3V, and requires no fixed bias voltage. The HMC643LC5 is housed in a compact 5x5 mm ceramic leadless SMT package 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. 10 PHASE SHIFTERS - DIGITAL - SMT Electrical Specifi cations, TA = +25° C, 50 Ohm System, Control Voltage = 0/-3V Parameter Frequency Range Insertion Loss* Input Return Loss* Output Return Loss* Phase Error* RMS Phase Error Insertion Loss Variation* Input Power for 1 dB Compression Input Third Order Intercept Control Voltage Current *Note: Major States Shown Min. 9 7 13 15 ±5 4.5 ±0.75 22 38
