Analog Devices Inc. ADL5350-EVALZ

Overview

ADL5350-EVALZ from Analog Devices is an evaluation board designed to characterize the ADL5350 GaAs pHEMT single-ended Y-mixer for RF/IF frequency conversion across 750 MHz–2.05 GHz. It supports up/down-conversion with 6.8 dB typical conversion loss, 25 dBm input IP3, and 6.5 dB noise figure at 1950 MHz receive operation, enabling rapid prototyping in cellular base station and point-to-point radio link designs.

For engineers reviewing the ADL5350-EVALZ datasheet, ADL5350-EVALZ pinout, ADL5350-EVALZ application, or ADL5350-EVALZ equivalent, this board provides full access to the ADL5350's RF/IF, LO, and supply terminals via SMA connectors and test points-supporting real-world validation of conversion loss, linearity, and LO drive sensitivity under controlled bias and filtering conditions.

Technical Context

The ADL5350-EVALZ implements a reference design matching the ADL5350's recommended layout per Analog Devices' Application Information section, including discrete LC filter networks for RF, IF, and LO ports. It uses 0603-size high-Q inductors and NP0/C0G capacitors optimized for 850 MHz and 1950 MHz low-side LO injection, with on-board bias chokes (L4) and dc-blocking capacitors (C3) aligned to Table 7 and Table 8 of the ADL5350 datasheet Rev. 0.

Board-level implementation follows the ADL5350's functional description: the LO buffer amplifier is biased through VPOS (Pin 6) with an RF choke, RF/IF ports (Pins 1 & 8) are externally tuned using series/parallel LC tanks, and ground integrity is maintained via dedicated GND1 (Pin 5), GND2 (Pin 2), and paddle connections. No baluns or differential circuitry are required due to the device's single-ended architecture.

FAQ

What is the primary function of the ADL5350-EVALZ?

The ADL5350-EVALZ is an evaluation board that enables full functional testing and performance validation of the ADL5350 high-linearity Y-mixer IC. It provides SMA-connected RF, IF, and LO interfaces, onboard biasing, and pre-tuned LC filter networks aligned to Analog Devices' reference design for 850 MHz and 1950 MHz receive operation.

Does ADL5350-EVALZ support both upconversion and downconversion?

Yes, ADL5350-EVALZ supports both upconversion and downconversion modes by reconfiguring external filter networks per the ADL5350's functional description. The board's RF/IF port symmetry and LO input flexibility allow it to operate with either low-side or high-side LO injection, as demonstrated in Figures 59 and 61 of the ADL5350 datasheet Rev. 0.

What power supply requirements does ADL5350-EVALZ have?

ADL5350-EVALZ requires a single 3 V DC supply capable of delivering up to 20 mA, consistent with the ADL5350's operating range of 2.7 V to 3.5 V and typical current draw of 16.5–19 mA at 4–6 dBm LO drive. The board includes decoupling capacitors and a series RF choke on the VPOS line per the ADL5350's Pin 6 implementation guidance.

Can ADL5350-EVALZ be used with frequencies outside the 750–2050 MHz range?

Yes - the ADL5350-EVALZ layout supports extension to lower (e.g., 136–176 MHz) and higher (e.g., 2560–2660 MHz) bands per the Applications Information section. Component values (e.g., L1, C1, L3, C3) must be adjusted per Table 8 and Figure 59/61; above 2.5 GHz, parasitic effects require careful selection of ultra-small high-Q passives.

Is the ADL5350-EVALZ RoHS compliant?

Yes, ADL5350-EVALZ is RoHS compliant, consistent with the ADL5350 IC's 8-lead LFCSP package and Analog Devices' environmental compliance policy. All PCB materials, solder mask, and surface finishes meet EU Directive 2011/65/EU requirements for hazardous substances.
