PE43712 Product Specification UltraCMOS RF Digital Step Attenuator, 9 kHz6 GHz Features Figure 1 PE43712 Functional Diagram Flexible attenuation steps of 0.25 dB, 0.5 dB and 1 dB up to 31.75 dB Switched Attenuator Array RF RF Glitch-less attenuation state transitions Input Output 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 Packaging32-lead 5 5 mm QFN Parallel Control Applications 7 3G/4G wireless infrastructure Serial In Control Logic Interface Land mobile radio (LMR) system Point-to-point communication system CLK LE A0 A1 A2 P/S Product Description The PE43712 is a 50, 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 and supports 1.8V control voltage and an extended operating temperature range to +105 C, making this device ideal for many broadband wireless applications. The PE43712 is a pin-compatible upgraded version of the PE43601 and PE43701. 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 PE43712 covers a 31.75 dB attenuation range in 0.25 dB, 0.5 dB and 1 dB steps. It is capable of maintaining 0.25 dB monotonicity through 4GHz, 0.5 dB monotonicity through 5 GHz and 1 dB monotonicity through 6 GHz. In addition, no external blocking capacitors are required if 0 VDC is present on the RF ports. The PE43712 is manufactured on pSemis UltraCMOS process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate. DOC-85209-4, Peregrine Semiconductor Corporation.

It is an innovative feature of the UltraCMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS. Absolute Maximum Ratings Exceeding absolute maximum ratings listed in Table 1 may cause permanent damage. Operation should be restricted to the limits in Table 2. Operation between operating range maximum and absolute maximum for extended periods may reduce reliability. ESD Precautions When handling this UltraCMOS device, observe the same precautions as with any other ESD-sensitive devices. Although this device contains circuitry to protect it from damage due to ESD, precautions should be taken to avoid exceeding the rating specified in Table 1. Latch-up Immunity Unlike conventional CMOS devices, UltraCMOS devices are immune to latch-up.
