PE43713

PE43713 Product Specification UltraCMOS® RF Digital Step Attenuator, 9 kHz–6 GHz Features Flexible attenuation steps of 0.25 dB, 0.5 dB and 1 dB up to 31.75 dB Glitch-less attenuation state transitions Monotonicity: 0.25 dB up to 4 GHz, 0.5 dB up to 5 GHz and 1 dB up to 6 GHz Extended +105 °C operating temperature Parallel and Serial programming interfaces with Serial Addressability Packaging—32-lead 5 × 5 mm QFN Applications Test and measurement (T&M) General purpose RF attenuator Figure 1 PE43713 Functional Diagram Switched Attenuator Array RF Input Parallel Control ×7 Serial In CLK Control Logic Interface LE RF Output A0 A1 A2 (optional) P/S VSS_EXT Product Description The PE43713 is a 50Ω, HaRP™ technology-enhanced, 7-bit RF digital step attenuator (DSA) that supports a broad frequency range from 9 kHz to 6 GHz. It features glitch-less attenuation state transitions, supports 1.8V control voltage and includes an extended operating temperature range to +105 °C and optional VSS_EXT bypass mode to improve spurious performance, making this device ideal for test and measurement (T&M). The PE43713 is a pin-compatible upgraded version of the PE43703. An integrated digital control interface supports both Serial Addressable and Parallel programming of the attenuation, including the capability to program an initial attenuation state at power-up. The PE43713 covers a 31.75 dB attenuation range in 0.25 dB, 0.5 dB and 1dB steps. It is capable of maintaining 0...
