NEW PE43702 9K~4GHz 0.25dB Stepping 31.75dB Digital RF Attenuator ModuleDescriptionFirst, product application: The PE43702 is a high linearity, 7-bit digital RF step attenuator with "DSA" ranging from 0.25 dB steps to 31.75 dB. The frequency range is attenuated from LF-4 GHz. This 50 ohm RF DSA provides parallel and serial CMOS control interfaces running on a single 5 volt supply and maintains high attenuation accuracy for frequency and temperature. It also has a unique control interface that allows the user to select the initial attenuation state at power up. It has a shielded case and an anti-reverse protection diode.Second, technical indicators 1, the supply voltage: 5V DC (typical current value 5mA) 2. Programmable gain attenuation range: 0 to 31.75DB Step 0.25DB input and output impedance: 50 ohms 3, the module supports parallel port and serial port mode function 4. Bandwidth: 9KHz to 4GHz (the attenuation values are different at different frequencies, please refer to the S21 curve indicator for details) 5, with metal shell shielding 6, provide test procedures and PDF file schematics package : 1pc NEW PE43702 9K~4GHz 0.25dB Stepping 31.75dB Digital RF Attenuator ModuleShippingItem will be shipped within 24 -48 hours after full payment is received.Normally the shippment to worldwide is used to take 25 to 30 business days, exclude Sat & Sun.PaymentWe accept PayPal only.Payment must be received in 7 business days of auction closing.Please leave note for your special request (e.g. Colors or Size) in ebay note when you pay the order.Any special request cannot be accepted after 24 hours of payment,because most of orders will be processed instantly and same day dispatched.Contact UsIf you have any questions, please feel free to email our servicer ，and we will reply you ASAP.
