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.

All device functions and configuration options can be accessed by a 3-wire or 4-wire Analog Devices, Inc., serial peripheral interface (SPI).

Two state machines are also integrated into the ADAR2001, which facilitate easy configuration, control, and fast switching of the frequency multiplier, filter, and transmitter sections. These sequencers are programmed through the SPI and are then operated by pulsed inputs (reset and advance).

The output power and chip temperature can be monitored by four on-chip detectors and a temperature sensor whose outputs are multiplexed to an 8-bit ADC.

The ADAR2001 requires only a single 2.5 V supply with power consumption of 450 mW with one channel turned on.

The ADAR2001 is available in a compact, 40-terminal, 6 mm × 6 mm LGA package and is specified from −40°C to +85°C.

Features and Benefits

  • Based on the ADAR2001 4-channel Frequency Multiplier/Filter
  • Controllable through SPI
  • Multiple forms of digital interface (3.3 V and 1.8 V logic)
  • On-board logic level translators with 1.8 V low dropout regulator for supply
  • Software control from a Windows-based PC through USB

Product Detail

The ADAR2001-EVALZ evaluation board is designed for testing the performance of the ADAR2001. The ADAR2001 is a 4-channel 4x Frequency Multiplier/Filter designed for mmWave security imaging applications. All RF input/outputs are brought out to 2.92mm (K) coaxial connectors. On-board logic level translators convert between the external logic level and the on-chip level of 1.8V.

There is an Analog Devices System Demonstration Platform (SDP) connector which can be used in conjunction with an SDP controller board to manipulate the internal registers as well as cycle through the programmed modes of the two internal state machines.

The ADAR2001 has two integrated state machines, one for the Multiplier section and another for the Transmitter section. The sequencers are configured through the SPI, and can be used to quickly cycle through pre-programmed states. These sequencers can be exercised in one of two ways:

  1. External Advance and Reset Pins:

    • TxADV - Transmitter Advance (Pin 8)
    • TxRST - Transmitter Reset (Pin 9)
    • MADV - Multiplier Advance (Pin 10)
    • MRST - Multiplier Reset (Pin 11)
  2. SPI writes to the SEQUENCER_CTRL_SPI register (0x44)

APPLICATIONS:

  • mmW Imaging
  • mmW Security
  • mmW Medical
  • mmW Industrial
  • Wideband LO Multiplier/Distributor
