Product details
Overview
HMC587LC4B from Analog Devices (formerly Hittite Microwave) is a wideband GaAs InGaP monolithic voltage-controlled oscillator with integrated buffer amplifier, operating from 5.0 to 10.0 GHz, delivering +5 dBm output power, -95 dBc/Hz SSB phase noise at 100 kHz offset, and tuned via 0–18 V analog voltage - used in radar, EW, and test instrumentation requiring stable wideband RF synthesis.
For engineers reviewing the HMC587LC4B datasheet, HMC587LC4B pinout, HMC587LC4B application, or HMC587LC4B equivalent, key selection criteria include its 5–10 GHz tuning range, +5V/55 mA single-supply operation, RoHS-compliant 4×4 mm SMT package, and verified phase noise performance across temperature (-40°C to +85°C).
Technical Context
The HMC587LC4B integrates resonator, negative resistance device, and varactor diode on a single GaAs InGaP MMIC die, eliminating external tuning components. Its monolithic construction ensures consistent phase noise and output power over temperature without external compensation.
It features a buffered RF output (AC-coupled), 0–18 V tuning port with ≤10 µA leakage at 18 V, and exhibits 4 MHz peak-to-peak frequency pulling into 2.0:1 VSWR - indicating robust load isolation for system-level integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 5.0 – 10.0 GHz: Full continuous tuning coverage enables single-VCO replacement of multiple narrowband oscillators in wideband systems. |
| Output Power | +5 dBm typical: Sufficient drive level to directly interface with mixers or prescalers without external amplification in most RF signal chains. |
| SSB Phase Noise @ 100 kHz | -95 dBc/Hz: Meets stringent spectral purity requirements for high-resolution radar and low-jitter sampling clock generation. |
| Tuning Voltage Range | 0 – +18 V: Enables wide modulation bandwidth and compatibility with standard DACs or analog control circuits. |
| Supply Current | 55 mA @ +5 V: Low power consumption supports thermally constrained modules and portable test equipment. |
| Operating Temperature | -40°C to +85°C: Validated performance across industrial and military environmental ranges without derating. |
| Package | 4 × 4 mm SMT alumina body with exposed ground paddle: Requires RF grounding per layout guidelines to maintain specified phase noise and output return loss ≥7 dB. |
Pinout & Package
RoHS-compliant 4 × 4 mm surface-mount package with alumina body, gold-over-nickel plating, and exposed ground paddle requiring solder connection to PCB RF ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–3, 5–11, 13, 17–24 | No Connection | Internally unconnected; may be tied to RF/DC ground without affecting performance. |
| 4 | Vtune | Analog tuning input (0–18 V); modulation bandwidth depends on source impedance - requires low-Z driver for wideband FM. |
| 12 | Vcc | +5 V DC supply input; bypassing with 1000 pF (0402) and 4.7 µF tantalum capacitors is mandatory for stable operation. |
| 14, 16 | GND | Ground terminals; must be soldered to PCB ground plane along with exposed bottom paddle to ensure thermal and RF stability. |
| 15 | RFOUT | AC-coupled RF output; requires external DC blocking capacitor and 50 Ω impedance match to preserve output return loss ≥7 dB. |
Key Features
| Feature | Design Value |
|---|---|
| Wide tuning bandwidth | 5.0–10.0 GHz continuous coverage eliminates need for band-switching VCOs or PLL reconfiguration in multi-band systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wideband VCO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC513LP5 | 5.5–10.5 GHz range, -92 dBc/Hz @ 100 kHz, +4.5 dBm output, requires +8 V supply. | Narrower tuning linearity and higher supply voltage limit use in low-voltage portable systems. | Prefer when extended upper-frequency margin (>10 GHz) is required and higher supply voltage is acceptable. |
| ADF4371 | Integrated PLL+VCO, 6.5–16.0 GHz, -110 dBc/Hz @ 100 kHz, but consumes 320 mA and requires external loop filter. | Higher integration adds complexity and power; superior phase noise comes at cost of size, heat, and design effort. | Choose when ultra-low phase noise and programmability outweigh size, power, and simplicity constraints. |
Compared with HMC587LC4B, HMC513LP5 offers wider top-end frequency but demands higher supply voltage and delivers lower output power, while ADF4371 provides vastly better phase noise and digital control at significantly higher current, board area, and design overhead - making HMC587LC4B optimal for analog-tuned, low-power, space-constrained wideband RF systems.

FAQ
What is the recommended PCB layout practice for HMC587LC4B?
For optimal RF and thermal performance, the HMC587LC4B's exposed ground paddle and pins 14/16 must be soldered to a solid RF ground plane using multiple thermal vias. Signal traces should maintain 50 Ω impedance, and Vcc must be decoupled with a 1000 pF 0402 capacitor and 4.7 µF tantalum capacitor close to pin 12. The HMC587LC4B evaluation board (108646) uses Rogers 4350 substrate and is available upon request from Analog Devices.
Does HMC587LC4B require external tuning components?
No, the HMC587LC4B is a fully monolithic VCO integrating the resonator, negative resistance device, and varactor diode - no external inductors, capacitors, or resonators are needed. Tuning is achieved solely via the 0–18 V analog voltage applied to pin 4 (Vtune), making it ideal for compact, high-reliability RF designs where component count and layout sensitivity must be minimized.
What is the maximum allowable tuning voltage for HMC587LC4B?
The absolute maximum rating for Vtune is +22 V, but the specified functional tuning range is 0 to +18 V. Operating beyond +18 V may cause irreversible damage or parametric shift. For reliable long-term operation, keep Vtune within 0–18 V, and ensure leakage current remains ≤10 µA at +18 V - verified per datasheet electrical specifications.
Can HMC587LC4B operate outside the -40°C to +85°C range?
No - the HMC587LC4B is characterized and guaranteed only from -40°C to +85°C. While junction temperature must not exceed 135°C, storage temperature extends to -65°C to +150°C. Operation outside the rated ambient range risks parametric drift, increased phase noise, or permanent degradation. Derating is not defined beyond +85°C, and thermal resistance (80 °C/W) assumes proper paddle grounding.
Is HMC587LC4B pin-compatible with other Hittite VCOs in the LC4B package?
No documented pin-compatible replacements exist within the LC4B family. Pinout is unique to the HMC587LC4B: Vtune is on pin 4, Vcc on pin 12, RFOUT on pin 15, and GND on pins 14/16 - differing from HMC513LP5 (QFN) and HMC514LP5 (same package but different pin mapping). Always verify pin functions against the official HMC587LC4B datasheet before board reuse.
