Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADAR4002ACPZ is an extremely low power wideband bidirectional single-channel true time delay unit (TDU) and digital stepping attenuator (DSA). The IC has a bandwidth of 18.5 GHz, a frequency range of 0.5GHz to 19 GHz, and an input impedance of 50 Ω on both RF ports. The TDU has two programmable maximum delays, both with 7-bit control: Range 0 has a maximum delay of 508ps and a resolution of 4ps. This range is used at lower frequencies and the loss of the ADAR4002 is low.
