These highly versatile DSAs cover a 31.75 dB attenuation range in 0.25 dB, 0.5 dB, or 1.0 dB steps. The customer can choose which step size and associated specifications are best suited for their application. PE43704 and PE43705 provide multiple CMOS control interfaces which support Direct Parallel, Latch Parallel, and Serial programming modes, and PE43704 has an optional external VSS feature. PE43704 and PE43705 maintain high attenuation accuracy over frequency and temperature, and exhibit low broadband insertion loss and low power consumption. Performance does not change with VDD due to an on-board regulator. These DSAs are available in a 32-lead 5x5 mm QFN footprint. No blocking capacitors are required if DC voltage is not present on the RF ports. The PE43704 and PE43705 Evaluation Kit (EVK) includes the application software and hardware required to control and evaluate the functionality of the DSA using a PC running the Windows operating system to control the USB interface board.

All rights reserved. PE43704 / PE43705 Evaluation Kit Manual Hardware Operation 1. Verify that all DC power supplies are turned off before proceeding. 2. Connect the jumper on HDR1. 3. Position the P/S switch to Parallel or Serial mode. 4. Set A0, A1, and A2 to “LOW” on HDR4 for default setting. They can be set to “HIGH” or “LOW” for Serial Addressable mode when more of the DSAs are used. Refer to Application Note AN26 on Peregrine Semiconductor’s website. 5. Set the D0~D6 programming switches to support Direct Parallel, Latched Parallel, or Serial mode. a) Place D0~D6 at the middle position to support Latched Parallel and Serial modes with GUI application software and proper position of the P/S switch. b) In Direct Parallel mode, D0~D6 can be set to “HIGH” or “LOW” to manually program the attenuation state while LE (pin 15 of J1) is connected to “HIGH” without using the USB interface board and application software. 6. Provide external power supply to the HRD2 connector (refer to the Operating Ranges table in the datasheets). a) VDD is the positive power supply. b) VDD_DIG is the positive power supply for control signals and can be connected to VDD to simplify the test set-up. c) VSS is the external negative power supply for PE43704. It can also be shorted to GND enabling the internal negative voltage generator and simplifying the test set-up. PE43705 does not have this option. 7. Calibrate board trace loss with “THRU” trace between J10 and J11.
