What are the key features of AD6645ASV-105?
- 14-bit resolution at 105 MSPS enables direct IF sampling of wideband signals up to 200 MHz input frequency
- Outstanding SFDR performance reduces signal chain complexity by eliminating the need for additional filtering in RF receivers
- Low power 5 V supply operation with differential analog inputs optimized for 50 Ω impedance matching in RF system designs
What is AD6645ASV-105 used for?
The AD6645ASV-105 is designed for wideband IF digitization in cellular base station receivers, military radar front ends, and software-defined radio platforms requiring 14-bit accuracy at 105 MSPS sample rates. Its high SFDR and SNR performance enable direct conversion of IF signals without additional intermediate filtering stages, reducing component count and system cost. The device is also used in spectrum analyzers and electronic warfare systems where fast, high-resolution digitization of broadband analog inputs is critical.

Frequently Asked Questions
What resolution and sample rate does the AD6645ASV-105 provide for IF sampling in communications receivers?
The AD6645ASV-105 provides 14-bit resolution at a maximum sample rate of 105 MSPS, enabling direct digitization of IF signals up to 200 MHz input frequency. This combination supports wideband channel bandwidths in cellular base stations and radar receivers while maintaining excellent dynamic range across the full Nyquist band.
How does the AD6645ASV-105's SFDR performance benefit software-defined radio and radar system designs?
High SFDR on the AD6645ASV-105 means spurious tones generated by nonlinearities in the ADC are suppressed well below the signal level, allowing nearby interfering signals to be rejected without additional analog filtering. In software-defined radio and phased-array radar designs operating at 105 MSPS, this reduces the risk of false target detection caused by ADC-generated intermodulation products.
What supply voltage does the AD6645ASV-105 require, and how does this affect power budget planning in a multi-channel receiver?
The AD6645ASV-105 operates from a 5 V supply. In multi-channel IF sampling systems such as 4-channel or 8-channel radar receivers, the 5 V rail simplifies power distribution but requires careful thermal management, as each AD6645ASV-105 channel operating at 105 MSPS contributes several hundred milliwatts to the total system power budget.
When is the AD6645ASV-105 preferred over a lower-resolution 12-bit ADC for base station IF digitization?
The 14-bit resolution of the AD6645ASV-105 is preferred over 12-bit alternatives when the receiver must handle a wide instantaneous dynamic range exceeding 70 dB, such as in cellular base stations where a weak desired signal co-exists with a strong blocker. The 2 additional bits provide roughly 12 dB more dynamic range headroom, reducing the burden on AGC circuits and digital baseband filtering at 105 MSPS.
