Product details
Overview
107384-HMC493LP3 from Analog Devices (formerly Hittite Microwave) is a GaAs HBT MMIC static frequency divider operating from DC (square-wave input) to 18 GHz with divide-by-4 functionality, -4 dBm typical output power, -150 dBc/Hz SSB phase noise at 100 kHz offset, and single +5 V supply. It serves as a prescaler in high-frequency PLL systems for point-to-point radios and test equipment.
For engineers reviewing the 107384-HMC493LP3 datasheet, 107384-HMC493LP3 pinout, 107384-HMC493LP3 application, or 107384-HMC493LP3 equivalent, key selection criteria include input frequency range (DC–18 GHz), differential RF input capability, QFN-16 package thermal performance, and low-phase-noise operation in RF synthesis chains.
Technical Context
The 107384-HMC493LP3 implements a static CMOS-compatible divide-by-4 logic core using InGaP GaAs HBT technology, enabling operation down to DC with square-wave inputs and up to 18.5 GHz with sine-wave inputs. Its dual differential outputs support balanced signal routing and improved harmonic suppression.
It features two independent 5V supply pins (Vcc1/Vcc2), internal biasing optimized for wideband stability, and an exposed ground paddle requiring direct PCB RF grounding per MIL-STD-883 thermal guidelines. Input sensitivity varies with frequency band-e.g., -15 dBm typical at 16–18 GHz-and reverse isolation exceeds 55 dB with both outputs terminated.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Frequency Range | DC–18 GHz (square wave); 0.2–18.5 GHz (sine wave) - supports broadband PLL prescaling without external AC coupling below 200 MHz. |
| Output Frequency Range | DC–4.625 GHz - divided output spans microwave to RF bands, enabling local oscillator generation for X-band transceivers. |
| SSB Phase Noise | -150 dBc/Hz @ 100 kHz offset (Pin = 0 dBm, Fin = 6 GHz) - preserves system EVM in high-order QAM modems. |
| Output Power | -7 to -4 dBm (Fin = 0.5–18 GHz) - sufficient to drive subsequent GaAs or SiGe buffer stages without amplification. |
| Supply Current | 96 mA @ Vcc = +5 V - enables low-power RF subsystem design with <500 mW total dissipation at 85°C ambient. |
| Reverse Leakage | 55 dB (both RF outputs terminated) - minimizes feedthrough-induced spurs in cascaded divider chains. |
| Operating Temperature | -40°C to +85°C - qualified for outdoor wireless infrastructure and military-grade environmental operation. |
Pinout & Package
107384-HMC493LP3 is housed in a 3×3 mm, 16-lead leadless QFN package (MSL1, Sn/Pb finish) with exposed ground paddle requiring solder connection to PCB RF ground plane per Hittite land pattern AN-107.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4–9, 12, 13, 16 | No Connection | Unused bond pads; must remain unconnected and unstubbed to avoid parasitic resonance. |
| 2 | RF Input (IN) | Main single-ended RF input; requires external DC blocking capacitor for AC-coupled sources. |
| 3 | RF Input (IN) | Differential complement to pin 2; 180° out-of-phase for balanced drive or AC-grounded for SE mode. |
| 10 | RF Output (OUT) | Primary divided-by-4 output; delivers full-swing complementary logic-level waveform. |
| 11 | RF Output (OUT) | Complementary divided output, 180° out-of-phase with pin 10 - enables differential clock distribution. |
| 14, 15 | Vcc1, Vcc2 | Independent +5 V supply pins; both must be decoupled locally with 100 pF (0402) and 1000 pF (0603) capacitors. |
| GND | Ground | Exposed metal paddle on package underside - must be soldered to solid RF ground plane with ≥6 thermal vias. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low SSB phase noise | -150 dBc/Hz at 100 kHz offset enables <0.5° RMS jitter in 10 Gbps serial links when used in clock recovery loops. |
| Dual differential outputs | Pins 10 and 11 provide true complementary divided signals - eliminates need for external balun in IQ LO generation. |
| DC-coupled square-wave operation | Supports sub-200 MHz input without external AC coupling - simplifies baseband-to-RF interface in radar pulse generators. |
| Thermally robust QFN package | 84 °C/W junction-to-paddle thermal resistance allows continuous 593 mW dissipation at 85°C ambient with proper PCB layout. |
| ESD-hardened design | Class 1A HBM rating (≥250 V) ensures reliability during automated SMT assembly and handling in Class 0 ESD environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar frequency divider applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC493LP3E | RoHS-compliant; matte Sn finish; MSL1 reflow peak 260°C vs. 235°C for HMC493LP3 | Identical electrical specs and pinout; intended for lead-free assembly lines only | Select HMC493LP3E when RoHS compliance and Pb-free reflow are mandatory; otherwise HMC493LP3 offers legacy Sn/Pb compatibility. |
| HMC363LP4 | Divide-by-2; 0.1–20 GHz input; -148 dBc/Hz phase noise; same 3×3 mm QFN package | Higher max input frequency but different division ratio - requires redesign of PLL feedback dividers | Choose HMC363LP4 only if divide-by-2 is required and phase noise budget allows -2 dBc/Hz degradation; not drop-in compatible. |
Compared with HMC493LP3E and HMC363LP4, the 107384-HMC493LP3 provides optimal trade-off between division ratio, phase noise, and legacy process compatibility - making it preferred for cost-sensitive, non-RoHS-restricted RF infrastructure designs where divide-by-4 is architecturally fixed.

FAQ
What is the minimum input frequency supported by the 107384-HMC493LP3?
The 107384-HMC493LP3 supports DC input for square-wave signals, meaning it can divide arbitrarily low-frequency digital clocks. For sine-wave inputs, the minimum specified frequency is 0.2 GHz (200 MHz) at +25°C, with derating to 0.5 GHz at temperature extremes. This makes the 107384-HMC493LP3 suitable for both baseband clock conditioning and microwave prescaling applications.
Does the 107384-HMC493LP3 require external DC blocking on its RF inputs?
Yes - the 107384-HMC493LP3 RF inputs (pins 2 and 3) must be DC blocked using external series capacitors, as stated in the pin description. This protects internal bias networks from external DC offsets and ensures proper HBT transistor operating points. Typical values are 100 pF in 0402 package, placed immediately adjacent to the input pads per Hittite's recommended layout.
Can the 107384-HMC493LP3 operate with a supply voltage other than +5 V?
The 107384-HMC493LP3 is characterized and specified only at +5 V ±0.25 V (4.75–5.25 V). Absolute maximum rating is +5.5 V, but performance parameters-including output power, phase noise, and input sensitivity-are not guaranteed outside the 4.75–5.25 V range. The 107384-HMC493LP3 should not be operated at lower voltages like 3.3 V, as internal biasing is incompatible.
What is the purpose of the two separate Vcc pins (14 and 15) on the 107384-HMC493LP3?
Pins 14 and 15 are independent +5 V supply connections for separate internal circuit blocks within the 107384-HMC493LP3 die. Both must be connected to the same +5 V rail and individually decoupled with low-inductance capacitors (e.g., 100 pF + 1000 pF) to suppress supply noise coupling between divider core and output buffers. This dual-supply architecture improves PSRR and reduces inter-stage crosstalk.
Is the 107384-HMC493LP3 pin-compatible with the HMC493LP3E variant?
Yes - the 107384-HMC493LP3 and HMC493LP3E share identical pinout, package dimensions, electrical specifications, and thermal characteristics. The only differences are RoHS compliance (matte Sn vs. Sn/Pb finish) and MSL1 reflow profile (260°C vs. 235°C peak). Therefore, the 107384-HMC493LP3 may be substituted for HMC493LP3E in non-RoHS assemblies, and vice versa in lead-free processes, with no PCB changes required.
