Analog Devices Inc. EV1HMC8074LP6G

Overview

EV1HMC8074LP6G from Analog Devices is a quadband monolithic microwave integrated circuit (MMIC) voltage-controlled oscillator (VCO) covering 8.3–15.2 GHz across four independent frequency bands, delivering RF1 output power of –5 to +6 dBm and RF2 output of –15 to –4 dBm at +4.75 V supply, with typical SSB phase noise of –76 dBc/Hz at 10 kHz offset in Band 1 - used in high-stability VSAT and point-to-point radio transceivers.

For engineers reviewing the EV1HMC8074LP6G datasheet, EV1HMC8074LP6G pinout, EV1HMC8074LP6G application, or EV1HMC8074LP6G equivalent, key selection criteria include band-switching supply control (VC1–VC4), dual AC-coupled RF outputs with distinct power levels, tuning voltage range (0.5–13.0 V), phase noise performance across temperature (–40°C to +85°C), and 40-lead 6×6 mm LFCSP package grounding requirements.

Technical Context

The EV1HMC8074LP6G integrates four independent VCO cores sharing common tuning and RF ports, each activated by dedicated band supply pins (VC1–VC4); only one band may be powered at a time. Its monolithic MMIC structure eliminates external resonators and matching components, enabling stable operation under shock, vibration, and thermal stress.

Phase noise is optimized via on-die varactor diodes and negative resistance devices; RF1 and RF2 outputs are internally coupled with 10–15 dB inter-output isolation. Tuning sensitivity varies per band (75–1150 MHz/V), and pulling/pushing specifications (0.25 MHz_pp, 20 MHz/V) reflect robustness against load and supply variation.

Key Specifications

Pinout & Package

The EV1HMC8074LP6G uses a RoHS-compliant 40-lead lead frame chip scale package (LFCSP) with 6 mm × 6 mm body and 0.85 mm height. The exposed metal paddle (Pins 2, 4, 6, 24, 26, 28) must be soldered to a solid RF/DC ground plane for thermal and electrical performance.

FAQ

What frequency bands does the EV1HMC8074LP6G support?

The EV1HMC8074LP6G supports four discrete frequency bands: Band 1 (8.3–10.1 GHz), Band 2 (10.1–11.9 GHz), Band 3 (11.9–13.6 GHz), and Band 4 (13.6–15.2 GHz). Each band is selected by applying +4.75 V to its dedicated supply pin (VC1–VC4), and only one band may be active at a time. This quadband architecture enables broad spectrum coverage without external tuning elements.

How are the two RF outputs of the EV1HMC8074LP6G used in system design?

The EV1HMC8074LP6G provides RF1 (–5 to +6 dBm) as the primary high-power output for signal transmission and RF2 (–15 to –4 dBm) as a coupled low-power output for monitoring, feedback, or diversity paths. Both outputs are AC-coupled and require external DC blocking; RF2's lower power level minimizes interference while enabling real-time spectral analysis without attenuators.

What is the recommended grounding strategy for the EV1HMC8074LP6G package?

The EV1HMC8074LP6G requires solid RF/DC grounding of its exposed metal paddle (Pins 2, 4, 6, 24, 26, 28) to maintain thermal dissipation (θ_JA = 70 °C/W) and phase noise performance. A minimum 4×4 mm thermal pad with ≥6 vias to inner ground planes is recommended. N/C pins (1, 7, 9–21, 30–40) may also be grounded to enhance shielding without impacting functionality.

Does the EV1HMC8074LP6G require external matching components?

No, the EV1HMC8074LP6G integrates resonators, varactor diodes, and matching networks monolithically - eliminating all external tuning or matching components. Its RF1 output return loss exceeds 13 dB and RF2 exceeds 7.5 dB across all bands, enabling direct connection to 50 Ω traces or baluns without additional impedance transformation.

What is the tuning voltage range and sensitivity behavior of the EV1HMC8074LP6G?

The EV1HMC8074LP6G accepts a tuning voltage (VTUNE) from 0.5 V to 13.0 V, with band-dependent sensitivity: 75–200 MHz/V (Band 1), 75–225 MHz/V (Band 2), 100–250 MHz/V (Band 3), and 120–275 MHz/V (Band 4). Sensitivity increases with frequency, enabling finer resolution at higher bands - critical for narrow-channel spacing in modern microwave standards.
