Analog Devices Inc. EV1HMC1161LP5

Overview

EV1HMC1161LP5 from Analog Devices is an evaluation board for the HMC1161 monolithic microwave integrated circuit (MMIC) voltage-controlled oscillator (VCO), supporting dual-output frequency synthesis from 8.71 GHz to 9.55 GHz (RFOUT) and 4.355 GHz to 4.775 GHz (RFOUT/2), with 11 dBm RFOUT power, −115 dBc/Hz SSB phase noise at 100 kHz offset, and operation over −40°C to +85°C - used for local oscillator validation in point-to-point radios and test equipment.

For engineers reviewing the EV1HMC1161LP5 datasheet, EV1HMC1161LP5 application, EV1HMC1161LP5 pinout, or EV1HMC1161LP5 equivalent, this evaluation board enables rapid characterization of the HMC1161 VCO's tuning linearity, output power stability, phase noise performance, and half-frequency output integrity under real RF PCB conditions with SMA RF connectors and optimized 50 Ω layout.

Technical Context

The EV1HMC1161LP5 is a dedicated evaluation platform for the HMC1161 LP5 packaged VCO, implementing full RF signal routing, bias decoupling (C1–C8), and dc header interfaces (J5/J6) for VTUNE and VCC control. It uses Rogers 4350B substrate to maintain consistent impedance and thermal behavior across temperature.

Designed per Analog Devices' reference layout guidelines, the board integrates SMA connectors (J1–J4) for RFOUT and RFOUT/2, exposes all critical VCO pins including VTUNE (Pin 29), VCC (Pin 21), GND (Pins 5/11), RFOUT (Pin 19), and RFOUT/2 (Pin 12), and requires direct ground paddle connection via multiple vias to ensure optimal phase noise and power delivery.

FAQ

What is the EV1HMC1161LP5 used for?

The EV1HMC1161LP5 is an evaluation board designed exclusively to characterize the HMC1161LP5 VCO. It enables measurement of RFOUT and RFOUT/2 output power, tuning voltage response, phase noise, and frequency stability across temperature. Engineers use the EV1HMC1161LP5 to validate integration into synthesizer loops before committing to custom PCB designs.

Does the EV1HMC1161LP5 include the HMC1161LP5 IC?

Yes, the EV1HMC1161LP5 includes one mounted HMC1161LP5 VCO (32-lead LFCSP_VQ package) as U1 on the board. The board is shipped fully assembled with all passive components, SMA connectors, and dc headers installed, ready for immediate RF testing with external power supplies and spectrum analyzers.

What RF frequencies can be measured using the EV1HMC1161LP5?

The EV1HMC1161LP5 supports full characterization of the HMC1161LP5's dual outputs: RFOUT from 8.71 GHz to 9.55 GHz and RFOUT/2 from 4.355 GHz to 4.775 GHz. Its SMA interfaces and Rogers 4350B substrate maintain signal integrity up to 10 GHz, enabling accurate S-parameter and phase noise measurements within these bands.

How is power supplied to the EV1HMC1161LP5?

Power is delivered via J5 and J6 2 mm dc headers: J5 supplies VCC (5 V, 250 mA typical), and J6 supplies VTUNE (2 V to 13 V). Decoupling capacitors (C1–C8) provide multi-band filtering. External bench supplies or programmable sources must comply with HMC1161's absolute maximum ratings: VCC ≤ 5.5 V, VTUNE ≤ 15 V.

Is the EV1HMC1161LP5 RoHS-compliant?

Yes, the EV1HMC1161LP5 is RoHS-compliant. Both the HMC1161LP5 IC and all bill-of-materials components-including SMA connectors, capacitors, and the Rogers 4350B PCB-meet EU Directive 2011/65/EU requirements. The board carries no hazardous substances above threshold limits and is compatible with lead-free reflow profiles (MSL3, 260°C peak).
