The F1958 is part of Renesas' Glitch-Free™ family of digital 步 attenuators (DSAs) optimized for the demanding 要求 of base station (BTS) radio cards and numerous 其他 应用s. This device is offered in a compact 4mm × 4mm 24-VFQFPN 包裹 with 50? input and 输出阻抗 for ease of integration into the radio or RF system. The F1958 offers very 高 reliability due to its construction from a monolithic silicon die and has very low insertion loss with minimal distortion. Additionally, the device is designed to have extremely accurate attenuation levels. These accurate attenuation levels improve system SNR and/or ACLR by ensuring system 获得 is as close to the targeted level as possible. In addition, the very fast settling time in parallel mode is ideal for fast switching systems. Finally, the device uses our Glitch-Free™ technology in contrast to competing DSAs.

Evaluation Board for F1958 7-bit Digital 步 Attenuator
The F1958EVB is a fully populated evaluation board which allows the customer to easily evaluate the digital 步 attenuator. Attenuation may be set using either the F1958's parallel control input or its serial control input. A dip switch on the evaluation board allows one to set the attenuation 状态 without off-board connections to the control inputs.
The F1958EVS is a complete hardware and software solution that allows customers to digitally control the F1958EVB with a computer. The solution includes the F1958EVB board, a USB Digital Control Board and interface cables. The software, guides, and instructional videos are available for download/查看ing on this page.
