Product details
Overview
EV1HMC6475LC4B from Analog Devices is a wideband monolithic microwave integrated circuit (MMIC) voltage-controlled oscillator with integrated buffer amplifier, operating from 3.90 to 7.50 GHz, delivering +5 dBm output power, -106 dBc/Hz SSB phase noise at 100 kHz offset, and consuming only 53 mA from a +5 V supply - ideal for low-noise RF signal generation in compact test equipment and radar front-ends.
For engineers reviewing the EV1HMC6475LC4B datasheet, EV1HMC6475LC4B pinout, EV1HMC6475LC4B application, or EV1HMC6475LC4B equivalent, this page delivers verified tuning range, phase noise performance, thermal resistance, supply current behavior across temperature, and grounding-critical pin assignments for stable RF design integration.
Technical Context
The EV1HMC6475LC4B integrates resonator, negative resistance device, and varactor diode on a single MMIC die, enabling full self-contained oscillation without external resonators. Its Vtune port accepts 0–23 V analog control, delivering 3.9–7.5 GHz linear frequency sweep with typical sensitivity of ~200 MHz/V at +10 V.
Phase noise is optimized across temperature: -106 dBc/Hz @ 100 kHz and -130 dBc/Hz @ 1 MHz offset at +25 °C; pulling is limited to 7 MHz peak-to-peak into 2.0:1 VSWR, and pushing is 10 MHz/V - critical for systems requiring stable frequency under supply variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 3.90–7.50 GHz - covers full X-band and lower Ku-band, enabling single-VCO coverage of wide IF/RF synthesis paths. |
| Output Power | +5 dBm typ. - sufficient to drive mixers or prescalers without external amplification in most signal chain architectures. |
| SSB Phase Noise @ 100 kHz | -106 dBc/Hz - supports high-modulation-fidelity applications such as QAM-64/256 in satcom transceivers. |
| Tuning Voltage Range | 0 to +23 V - allows compatibility with standard DACs and analog loop filters without level-shifting circuitry. |
| Supply Current | 53 mA @ +5 V - enables low-power portable or battery-assisted RF subsystems with minimal thermal load. |

| Operating Temperature | -40 °C to +85 °C - qualified for industrial and military environmental stress profiles without derating. |
Pinout & Package
EV1HMC6475LC4B is housed in a 24-terminal ceramic leadless chip carrier (LCC), 4 mm × 4 mm × 1.1 mm body, with exposed metal paddle (pins 14 & 16) requiring solder connection to RF/DC ground plane for thermal and electrical integrity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar wideband VCO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC513LP5 | Narrower range (4.8–5.7 GHz); higher Pout (+10 dBm); same 24-lead LCC package but different pinout. | Limited to fixed-band radar or narrowband comms; lacks EV1HMC6475LC4B's X/Ku-band coverage. | Select when higher output power is prioritized over bandwidth and pin compatibility is not required. |
| ADF4372BCPZ | Integrated PLL+VCO; 6.4–13.6 GHz range; SPI-programmable; consumes 125 mA; requires external loop filter. | Enables fully synthesized LO generation but adds digital interface overhead and footprint; not drop-in compatible. | Choose when programmable frequency steps and phase synchronization are needed over analog tuning simplicity. |
Compared with HMC513LP5 and ADF4372BCPZ, the EV1HMC6475LC4B uniquely delivers widest analog-tuned bandwidth in a low-power, pin-defined LCC package - optimal for analog-centric RF systems where phase noise, size, and supply simplicity outweigh programmability needs.

FAQ
What is the absolute maximum tuning voltage for EV1HMC6475LC4B?
The absolute maximum rating for Vtune is +25 V DC. Exceeding this voltage risks permanent damage to the internal varactor diode. The recommended operating range is 0 to +23 V, where full 3.90–7.50 GHz tuning is guaranteed. EV1HMC6475LC4B datasheet Section "Absolute Maximum Ratings" specifies Vtune = –1 to +25 V, with leakage current ≤100 µA at +23 V.
Does EV1HMC6475LC4B require an external resonator or tank circuit?
No - EV1HMC6475LC4B is a fully integrated MMIC VCO containing monolithic resonator, negative resistance device, and varactor diode. No external inductors, capacitors, or crystals are needed. This integration eliminates tuning drift and layout sensitivity associated with discrete resonators, making EV1HMC6475LC4B suitable for high-reliability RF modules.
How should the exposed paddle (pins 14 and 16) of EV1HMC6475LC4B be connected?
The exposed paddle must be soldered directly to a solid RF/DC ground plane using a minimum of six 0.3-mm-diameter thermal vias spaced evenly beneath it. This connection is mandatory for both thermal dissipation (80 °C/W junction-to-ground) and RF return path integrity. Inadequate paddle grounding degrades phase noise and output power consistency in EV1HMC6475LC4B.
What is the typical supply current of EV1HMC6475LC4B across temperature?
Typical supply current is 53 mA at +25 °C and +5 V supply. It increases to 57 mA at +85 °C and decreases to 49 mA at –40 °C, as shown in Figure 7 of the EV1HMC6475LC4B datasheet. This low and stable current draw supports thermal management in dense RF assemblies where EV1HMC6475LC4B is deployed.
Can EV1HMC6475LC4B be used as a direct replacement for HMC6475LC4B?
Yes - EV1HMC6475LC4B is the evaluation board variant of the HMC6475LC4B die-in-package, designed for bench characterization. It uses the identical 24-lead LCC package, pinout, and electrical specifications. All EV1HMC6475LC4B performance data (phase noise, tuning range, power) matches the production HMC6475LC4B, making it functionally and physically interchangeable in prototype validation.
