Analog Devices Inc. 122826-HMC753LP4E

Overview

122826-HMC753LP4E from Analog Devices is an evaluation printed circuit board (PCB) designed for the HMC753LP4E GaAs MMIC low-noise amplifier, supporting RF characterization and system integration across 1 GHz to 11 GHz. It provides SMA-connected RF input/output, DC bias headers (VDD, VGG1, VGG2), and optimized decoupling with 100 pF, 1000 pF, and 4.7 µF capacitors on a Rogers 4350 or Arlon 25FR substrate.

For engineers reviewing the 122826-HMC753LP4E datasheet, 122826-HMC753LP4E application, or 122826-HMC753LP4E equivalent, this evaluation board enables rapid validation of HMC753LP4E small-signal gain (16.5 dB @ 1–6 GHz), noise figure (1.5 dB @ 4 GHz), P1dB (18 dBm), and 50 Ω matched I/O in microwave radio, test instrumentation, and VSAT designs.

Technical Context

The 122826-HMC753LP4E evaluation PCB implements the recommended biasing network per HMC753 datasheet Rev. E: VDD = 5 V, VGG1 ≈ −0.8 V, VGG2 = 1.5 V, delivering 55 mA quiescent current. It uses discrete 0402/0603 ceramic and tantalum capacitors for broadband RF and power supply decoupling across the full 1–11 GHz band.

Designed for direct mounting to a heat sink, the board features controlled-impedance 50 Ω microstrip traces, full ground plane connectivity via multiple vias, and exposed-pad grounding for the HMC753LP4E's LFCSP package - ensuring thermal stability and repeatable RF performance under +25°C, −40°C, and +85°C operating conditions.

FAQ

What is the purpose of the 122826-HMC753LP4E evaluation board?

The 122826-HMC753LP4E evaluation board is a fully assembled PCB designed to accelerate development with the HMC753LP4E GaAs MMIC low-noise amplifier. It provides calibrated RF paths, proper bias sequencing support, and thermal management to validate key parameters - including 16.5 dB gain at 4 GHz, 1.5 dB noise figure, and 18 dBm P1dB - without custom layout effort. The 122826-HMC753LP4E enables immediate lab testing and system-level integration.

Does the 122826-HMC753LP4E include the HMC753LP4E IC?

Yes, the 122826-HMC753LP4E evaluation board includes one mounted HMC753LP4E IC in its 24-lead LFCSP package (4 mm × 4 mm). The device is pre-soldered and electrically verified per Analog Devices' datasheet Rev. E specifications, with all required external bias and decoupling components populated - including SMA connectors, DC headers, and multi-value capacitor networks.

What are the required bias voltages for operating the HMC753LP4E on the 122826-HMC753LP4E board?

The 122826-HMC753LP4E board supports the recommended HMC753LP4E bias conditions: VDD = 5 V, VGG2 = 1.5 V, and VGG1 adjusted to achieve 55 mA quiescent current (typically ≈ −0.8 V). These values are specified in the HMC753 datasheet Rev. E and implemented via J1–J4 DC pin headers. Proper power-up sequence (GND → VGG1 → VDD → VGG2) must be followed to avoid damage to the 122826-HMC753LP4E-mounted HMC753LP4E.

Can the 122826-HMC753LP4E be used for production applications?

No - the 122826-HMC753LP4E is strictly an evaluation board intended for design validation, characterization, and prototyping. It is not qualified for volume production use due to its hand-soldered construction, non-industrial-grade mechanical tolerances, and lack of extended reliability testing. For production, designers must implement the HMC753LP4E into their own PCB using the layout guidelines, thermal requirements, and decoupling recommendations documented in the 122826-HMC753LP4E datasheet.

What substrate material is used in the 122826-HMC753LP4E PCB?

The 122826-HMC753LP4E evaluation board uses either Rogers 4350 or Arlon 25FR high-frequency laminate - both low-loss dielectrics with stable ε_r (~3.48–3.6) and tight impedance control. This ensures minimal RF loss and consistent 50 Ω microstrip performance from 1 GHz to 11 GHz, directly supporting accurate measurement of the HMC753LP4E's gain flatness, return loss, and IP3 metrics.
