7-Bit 0.25dB Digital Step Attenuator F1958 1MHz to 6GHz Datasheet Description Features TM The F1958 is part of IDTs Glitch-Free family of DSAs optimized Serial and 7-bit parallel interface for the demanding requirements of Base Station (BTS) radio cards 31.75dB range and numerous other applications. This device is offered in a 0.25dB steps compact 4mm x 4mm 24-pin package with 50 input and output TM Glitch-Free : low transient overshoot impedance for ease of integration into the radio or RF system. 500ns settling time for 0.25dB steps The F1958 offers very high reliability due to its construction from a Ultra linear > 63dBm IIP3 monolithic silicon die in a QFN package. The insertion loss is very Low insertion loss < 1.7dB at 4GHz low with minimal distortion. Additionally, the device is designed to have extremely accurate attenuation levels. These accurate Attenuation error < 0.2dB at 4GHz attenuation levels improve system SNR and/or ACLR by ensuring Bi-directional RF use system gain is as close to the targeted level as possible. In addition, 3.3V or 5V supply the very fast settling time in parallel mode is ideal for fast switching TM -40C to +105C operating temperature systems. Finally, the device uses our Glitch-Free technology in contrast to competing DSAs. 4mm x 4mm Thin QFN 24-pin package Block Diagram Competitive Advantage Figure 1.
