Product details
Overview
HMC515LP5 from Analog Devices (formerly Hittite Microwave) is a GaAs InGaP HBT MMIC voltage-controlled oscillator with integrated divide-by-4 and half-frequency outputs, operating at 11.5–12.5 GHz fundamental frequency, +10 dBm RFOUT power, −110 dBc/Hz phase noise @ 100 kHz offset, and packaged in a 32-lead 5×5 mm QFN. It serves as a compact, self-contained RF source in microwave transceivers.
For engineers reviewing the HMC515LP5 datasheet, HMC515LP5 pinout, HMC515LP5 application, or HMC515LP5 equivalent, this page delivers verified specifications, dual-output timing context, package-aware layout guidance, and real-world alternative options for VSAT, point-to-point radio, and test equipment design.
Technical Context
The HMC515LP5 integrates monolithic resonators, varactor tuning, and on-die prescaler logic to deliver three synchronized RF outputs: Fo (11.5–12.5 GHz), Fo/2 (5.75–6.25 GHz), and Fo/4 (~2.875–3.125 GHz). Its GaAs HBT process ensures stable phase noise across −40°C to +85°C without external matching.
Supply is split across Vcc1 (prescaler, disableable) and Vcc2 (core oscillator), enabling current optimization. Tuning is via VTUNE (2–13 V), with 6 MHz/V pushing and 8 MHz pp pulling tolerance into 2.0:1 VSWR - critical for PLL loop stability in narrow-channel systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Fo Range | 11.5–12.5 GHz - defines usable carrier band for Ku-band VSAT uplinks and military SATCOM terminals. |
| Fo/2 Output | 5.75–6.25 GHz - provides low-phase-noise local oscillator signal for downconversion without external dividers. |
| RFOUT Power | +10 dBm typical - sufficient to drive mixer LO ports directly, reducing need for buffer amplifiers. |
| Phase Noise | −110 dBc/Hz @ 100 kHz offset - meets stringent spectral purity requirements for high-order QAM modulation. |
| Supply Current | 200 mA typical @ +5 V - enables thermal management in compact SMT RF modules with ≤1.43 W max dissipation. |
| Tuning Range | 2–13 V - supports wide-loop PLL designs and analog FM modulation without external level-shifting. |
| Package | 32-lead 5×5 mm QFN with exposed paddle - requires RF ground via array under die for optimal thermal and EMI performance. |
Pinout & Package
Package: 32-lead leadless QFN, 5×5 mm body, exposed ground paddle, Sn/Pb finish, MSL3 rating. Requires soldering of all ground leads and paddle to PCB RF ground per Hittite land pattern guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–3, 7–10, 13–18, 20, 22–28, 30–32 | N/C | No connection; may be grounded for mechanical stability without affecting RF performance. |
| 4 | RFOUT/4 | AC-coupled divide-by-4 output (~2.875–3.125 GHz); usable as low-jitter clock or IF source. |
| 6 | Vcc1 | Prescaler supply (+5 V); open to disable prescaler and reduce current by ~65 mA. |
| 12 | RFOUT/2 | AC-coupled half-frequency output (5.75–6.25 GHz); isolated from core oscillator for clean LO generation. |
| 19 | RF OUT | AC-coupled fundamental output (11.5–12.5 GHz); primary RF source with +10 dBm typical power. |
| 21 | Vcc2 | Main oscillator supply (+5 V); must be powered for all outputs to function. |
| 29 | VTUNE | Control voltage input (2–13 V); modulates frequency linearly with 6 MHz/V pushing sensitivity. |
| 5, 11, Paddle | GND | RF/DC ground reference; paddle must be soldered to solid ground plane with multiple vias for thermal and EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| Dual synchronized outputs (Fo, Fo/2) | Enables single-device LO generation for both uplink and downlink paths in full-duplex radios. |
| Integrated divide-by-4 output | Eliminates need for external prescalers in frequency synthesis chains, reducing bill-of-materials and board area. |
| No external resonator required | Monolithic GaAs HBT structure delivers stable oscillation without discrete inductors/capacitors or tuning screws. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar VCO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC516LP5 | Fo = 12.5–13.5 GHz; identical package, pinout, and architecture; +9 dBm RFOUT; −109 dBc/Hz phase noise @ 100 kHz. | Higher-frequency variant for extended Ku-band or lower Ka-band use; not interchangeable without RF front-end redesign. | Select HMC516LP5 only when system requires >12.5 GHz carrier - same layout but different filter/matching network. |
| ADF4371BCPZ | Silicon-based PLL+VCO; Fo = 1–8 GHz; integrated fractional-N synthesizer; −111 dBc/Hz phase noise @ 100 kHz; 32-lead 7×7 mm LFCSP. | Programmable frequency step (1 Hz), no Fo/2 or Fo/4 outputs; requires external loop filter and reference clock. | Choose ADF4371BCPZ for digitally tuned, fine-resolution synthesis; HMC515LP5 remains preferred for analog-tuned, multi-output simplicity. |
Compared with HMC516LP5 and ADF4371BCPZ, the HMC515LP5 uniquely delivers fixed-range, ultra-low-phase-noise Fo/Fo/2/Fo/4 outputs in a compact 5×5 mm QFN - ideal where analog tuning, minimal external components, and multi-output coherence outweigh programmability needs.

FAQ
What is the fundamental output frequency range of the HMC515LP5?
The HMC515LP5 delivers a fundamental RF output (RF OUT) from 11.5 to 12.5 GHz. This range is fully specified and tested across temperature and supply voltage variations, making it suitable for Ku-band applications such as satellite uplinks and licensed microwave links. The HMC515LP5 achieves this with no external resonator or tuning components required.
Does the HMC515LP5 provide multiple output frequencies from a single device?
Yes, the HMC515LP5 provides three synchronized RF outputs: fundamental (Fo = 11.5–12.5 GHz), half-frequency (Fo/2 = 5.75–6.25 GHz), and divide-by-4 (Fo/4 ≈ 2.875–3.125 GHz). All outputs are internally generated and AC-coupled, enabling coherent LO distribution in transceivers without external dividers - a key feature of the HMC515LP5 architecture.
Can the prescaler section of the HMC515LP5 be disabled to reduce power consumption?
Yes, the prescaler section of the HMC515LP5 is powered separately via Pin 6 (Vcc1). Leaving Vcc1 unconnected disables the prescaler and reduces total supply current by approximately 65 mA. This feature is explicitly supported in the HMC515LP5 datasheet and allows optimized power use when only Fo and Fo/2 outputs are needed.
What is the recommended grounding practice for the HMC515LP5 QFN package?
The HMC515LP5 requires all ground pins (Pins 5, 11) and the exposed metal paddle to be soldered to a solid RF/DC ground plane using multiple thermal vias. Per Hittite's application note, this minimizes thermal resistance (35 °C/W junction-to-paddle), suppresses ground bounce, and ensures repeatable phase noise and output power - essential for reliable HMC515LP5 operation.
Is the HMC515LP5 RoHS-compliant?
The HMC515LP5 uses Sn/Pb lead finish and is not RoHS-compliant; the RoHS-compliant variant is the HMC515LP5E (with 100% matte Sn finish and MSL3 reflow profile up to 260 °C). Both share identical electrical specifications and pinout, but material compliance differs - verify version before procurement to meet environmental requirements for the HMC515LP5 or HMC515LP5E.
