F1958NBGK8 General Description

The F1958 is part of IDT’s Glitch-Free™ family of DSAs optimized for the demanding requirements of Base Station (BTS) radio cards and numerous other applications. This device is offered in a compact 4 × 4 mm 24-VFQFPN package with 50Ω input and output impedance for ease of integration into the radio or RF system. The F1958 offers very high 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 gain 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.
