The ADMV4530 is a highly integrated upconverter with an in-phase/quadrature (I/Q) mixer that is ideally suited for next generation Ka band satellite communications.

An integrated low phase noise, fractional-N phase-locked loop (PLL) with a voltage controlled oscillator (VCO) and internal 2× multiplier generate the necessary on-chip local oscillator (LO) signal for the I/Q mixer, eliminating the need for external frequency synthesis. The VCO uses an internal autocalibration routine that allows the PLL to select the necessary settings and locks in approximately 100 µs.

The single-ended reference input to the PLL operates up to 500 MHz and features internal reference dividers and a multiplier for added flexibility. Additionally, the phase frequency detector (PFD) comparison frequency can be up to 250 MHz for integer mode and 160 MHz for fraction-N mode.

The upconverter consists of an I/Q mixer that can operate in either I/Q mode with 500 MHz of bandwidth or in IF mode up to 3 GHz of bandwidth, which allows various radio architectures and backward compatibility with legacy systems.

Immediately following the I/Q mixer are stages of gain and variable attenuation. The configuration can achieve a minimum 1 dB compression point (P1dB) compression point of 19 dBm, eliminating the need for external stages of gain.

A programmable 4-wire serial port interface (SPI) allows adjustment of the quadrature phase for optimum sideband suppression. In addition, the SPI allows nulling of LO feedthrough in IF mode. In I/Q mode, the LO feedthrough can be nulled by applying external dc offset to the differential baseband I/Q inputs.

An IF automatic gain control (AGC) adjusts the IF variable gain amplifier (VGA) to compensate for input power variations. During normal operation, this AGC feature can be enabled or disabled via the SPI. When disabled during normal operation, the AGC feature only works on a test tone during power-down mode to track temperature variations.

The ADMV4530 upconverter comes in a RoHs compliant, 6 mm × 6 mm, 40-terminal land grid array (LGA) package. The ADMV4530 operates over the −40°C to +85°C case temperature range.

ADMV4530 Evaluation Board

Features and Benefits

  • Fully featured evaluation board for the ADMV4530
  • On-board system demonstration platform (SDP-S) connector for SPI
  • 5 V operation through LDO
  • ACE software interface for SPI control

Product Detail

The ADMV4530IQ-EVALZ and the ADMV4530IF-EVALZ are the two evaluation boards available for the ADMV4530 that work in inphase/quadrature (I/Q) mode and intermediate frequency (IF) mode, respectively. Both boards incorporate the ADMV4530 Ka band upconverter with low dropout (LDO) regulators and an interface to the EVAL-SDP-CS1Z (SDP-S) controller board to allow the simple and efficient evaluation of the ADMV4530. The on-board LDO regulators allow the ADMV4530 to be powered on by a single supply.

The ADMV4530 is a highly integrated upconverter with an I/Q mixer that is ideally suited for next generation Ka band satellite communications. The chip can be programmed using a 4-wire serial port interface (SPI). The SDP-S controller allows the user to interface with the ADMV4530 SPI through the Analog Devices, Inc., Analysis, Control Evaluation (ACE) software.

For full details on the ADMV4530, see the ADMV4530 data sheet, which must be consulted in conjunction with this user guide when using the ADMV4530IQ-EVALZ and the ADMV4530IF-EVALZ.
