Product Specification PE4309 Product Description This product is a high linearity, 6-bit RF Digital Step Attenuator (DSA) covering a 31.5 dB attenuation range in 0.5 dB steps. The Peregrine 50Ω RF DSA provides a parallel CMOS control interface and it operates on 3-volt to 5-volt supply. It maintains high attenuation accuracy over frequency and temperature and exhibits very low insertion loss and low power consumption. This Peregrine DSA is available in a 4x4 mm 24 lead QFN footprint with an exposed ground paddle. The PE4309 is manufactured on Peregrine’s UltraCMOS™ process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.

Connect J2 by mini clip to Vdd to power the IC. Connect J8 by mini clip to power the evaluation board support circuits. The control bits for the six parallel data inputs (C0.5 to C16) are controlled using S2-S7 to select bits or bit combinations. This allows any attenuation setting to be specified as shown in Table 6. The de-embed trace (J6 to J7) estimates the PCB insertion loss for removal from the evaluation board measurement data. To evaluate using customer software, J1 can be installed using a standard 0.100 IDC header (some circuit modification required, see schematic). The ability to supply different voltages for the Control circuitry (using J8) and IC Vdd (using J2) circuits allows for evaluation of circuits using different control vs. supply voltages. Figure 5.
