PE43508

PE43508 Document Category: Product Specification UltraCMOS® RF Digital Step Attenuator, 9 kHz–55 GHz Features Wideband support up to 55 GHz Glitch-safe attenuation state transitions Flexible attenuation steps of 0.5 dB and 1 dB up to 31.5 dB Extended +105 °C operating temperature Parallel and serial programming interfaces with serial addressability Flip-chip die Figure 1 PE43508 Functional Diagram Switched Attenuator Array RF Input RF Output Applications Test and measurement (T&M) Point-to-point communication systems Very small aperture terminals (VSAT) Parallel Control 6-bit Serial In CLK Control Logic Interface Serial Out LE A0 A1 A2 (optional) P/S VDD VSS_EXT Product Description The PE43508 is a 50Ω, HaRP™ technology-enhanced, 6-bit RF digital step attenuator (DSA) that supports a wide frequency range from 9k to 55 GHz. The PE43508 features glitch-safe attenuation state transitions, supports 1.8V control voltage and optional VSS_EXT bypass mode to improve spurious performance, making this device ideal for test and measurement, point-to-point communication systems, and very small aperture terminals (VSAT). The PE43508 provides an integrated digital control interface that supports both serial addressable and parallel programming of the attenuation. The PE43508 covers a 31.5 dB attenuation range in 0.5 dB and 1 dB steps. It is capable of maintaining 0.5 dB and 1 dB monotonicity through 55 GHz. In addition, no external blocking capacitors are req...
