The ADAR2001 is a transmitter IC optimized for millimeter wave body scanning applications. Accepting a single-ended continuous wave (CW) input signal between 2.5 GHz and 10 GHz, the ADAR2001 provides gain, 4× frequency multiplication, harmonic filtering, 1:4 signal splitting, and four independently controllable power amplifiers (PAs) with differential outputs designed to directly drive dipole antennas with differential inputs.
Key Features and Benefits
● Offers operation in the 10 – 40 GHz frequency range, provides sufficient resolution to detect and identify small objects while also providing penetration of clothing to allow walk-through operation.
● Fast switching and configuration - via advanced sequencers (state machines) simplifies design of large array systems while maintaining the efficiency and speed of operation to successfully scan these large arrays
● Highly integrated SiGe device featuring the critical signal chain elements for multi-channel Tx signal paths in mmWave arrays – all in a convenient LGA form-factor. Simplifies the design and operation of large mmWave scanning arrays by eliminating the need to distribute high frequencies (up to 40 GHz) and providing a cost-effective path towards developing modular (tiled) arrays
Applications
● Aerospace and Defense: mmWave Security Scanner Imager
● Communications: Multi-Channel Tx; LO multiplication and distribution
● Instrumentation: Multi-Channel Tx; LO multiplication and distribution
● Healthcare: Multi-Channel Tx as part of Imager system
Evaluation Board
