Product details
Overview
HMC813-SX from Analog Devices (formerly Hittite Microwave) is a Successive Detection Log Video Amplifier (SDLVA) designed for RF power measurement and logarithmic amplitude detection in high-speed channelized receivers. It operates from 1 to 20 GHz, delivers 55 dB logging range with ±1 dB log linearity (−40 to 0 dBm), features 5 ns rise / 10 ns fall time, and outputs a 15 mV/dB log video signal referenced to a single +3.3 V supply. It is deployed in EW/ELINT receivers where wideband dynamic range and nanosecond-level response are critical.
For engineers reviewing the HMC813-SX datasheet, HMC813-SX pinout, HMC813-SX application, or HMC813-SX equivalent, this page provides verified technical context, package mapping, real-world use scenarios, and validated alternative options - all grounded in the official HMC813LC4B datasheet (v03.0614), which defines the HMC813-SX as the same device in a 24-lead 4×4 mm ceramic SMT package.
Technical Context
The HMC813-SX implements a cascaded successive-detection architecture across multiple gain stages to achieve broadband logarithmic response from 1–20 GHz. Its RF input and output are differential-capable but commonly used single-ended with AC-coupled termination, and its log video output is DC-coupled with 0.9–1.73 V swing over full dynamic range.
It integrates three independent bias supplies (VCC1, VCC2, VCC3), an enable pin (EN) reducing supply current to <3 mA in standby, and requires RF/DC grounding of 16 pins plus the exposed paddle. The device meets Class 1A HBM ESD rating and operates across −55°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 1–20 GHz: Full log response usable across entire band without recalibration or switching. |
| Logging Range | 55 dB: Input power range (−53 to +7 dBm at 18 GHz) delivering ±3 dB log error - enables detection of weak signals amid strong interferers. |
| Log Linearity | ±1 dB (−40 to 0 dBm): Ensures accurate amplitude estimation for pulse-width and amplitude-modulated RF signals. |
| Rise/Fall Time | 5 ns / 10 ns: Supports pulse detection down to ~200 MHz repetition rate; critical for fast-scan DF and ECM systems. |
| Supply Voltage | +3.3 V single supply: Simplifies power design; total current draw is 153 mA in active mode. |
| Output Slope | 15 mV/dB: Direct voltage-to-power mapping enables analog-to-digital conversion without lookup tables. |
| Operating Temp | −55°C to +85°C: Qualified for military airborne, ground, and space-qualified platforms per MIL-STD-883. |
Pinout & Package
Package: 24-lead 4×4 mm ceramic SMT (alumina body, gold-over-nickel plating, MSL3). Exposed ground paddle must be soldered to PCB RF ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–3, 6–9, 11–13, 19, 24 | N/C | Internally unconnected; externally grounded to minimize parasitic coupling and improve RF return loss. |
| 4, 5 | RFINP, RFINN | Differential RF input; single-ended operation uses RFINP with RFINN AC-coupled to 50 Ω ground. |
| 10 | VIDEO OUT | DC-coupled log video output; requires ≥1 kΩ load for specified slope and linearity. |
| 14, 15 | RFOUTN, RFOUTP | Differential RF output; single-ended use connects RFOUTP to load, RFOUTN AC-coupled to 50 Ω ground. |
| 16, 18 | GND | Dedicated RF/DC ground pins; must connect to low-inductance ground plane alongside exposed paddle. |
| 17 | EN | Active-high enable; pulls supply current from 153 mA to <3 mA when low - enables rapid power gating. |
| 20, 22, 23 | VCC3, VCC1, VCC1 | Bias supply inputs; require local 100 nF ultra-wideband decoupling per pin per datasheet layout guidelines. |
| 21 | VCC2 | Secondary bias supply; same decoupling and rise-time requirements (<100 µs) as other VCC pins. |
Key Features
| Feature | Design Value |
|---|---|
| 55 dB logging range with ±1 dB linearity | Enables precise RF amplitude measurement across five decades of input power without digital correction. |
| 5 ns rise / 10 ns fall time | Supports pulse detection in fast-scan electronic warfare receivers with minimal temporal smearing. |
| Single +3.3 V supply, 153 mA | Reduces board-level power conversion complexity and thermal load in dense RF front-end modules. |
| Class 1A HBM ESD rating | Allows safe handling and assembly in standard production environments without special ESD controls beyond baseline. |
| −55°C to +85°C operating range | Validates use in extended-temperature military platforms including radar seekers and UAV payloads. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar log video amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1099LP4E | 2–18 GHz range, 45 dB logging range, 10 ns rise time, +5 V supply, 200 mA current. | Lower bandwidth and dynamic range; suited for lower-cost EW subsystems where 20 GHz coverage is not required. | Select when system bandwidth ceiling is ≤18 GHz and higher supply voltage is acceptable. |
| LT5537 | 1–1000 MHz range, 65 dB range, 300 ns response, +3.3 V supply, 22 mA current. | Narrowband LF/MF/HF only; unsuitable for microwave EW but ideal for IF-stage monitoring or baseband power control. | Choose only for sub-GHz applications requiring ultra-low power and wider log range at cost of speed and frequency. |
Compared with HMC813-SX, HMC1099LP4E trades 2 GHz upper-bandwidth and 10 dB logging range for broader industry availability, while LT5537 offers superior low-frequency resolution and power efficiency but cannot operate above 1 GHz - making HMC813-SX uniquely qualified for 1–20 GHz real-time pulse analysis.

FAQ
What is the operating frequency range of the HMC813-SX?
The HMC813-SX operates from 1 GHz to 20 GHz with flat frequency response (±1.5 dB) and full logarithmic functionality across the band. Its minimum logging range is −53 dBm and maximum is +7 dBm at 18 GHz, supporting wideband signal interception and analysis in military RF systems.
Does the HMC813-SX require multiple supply voltages?
Yes - the HMC813-SX requires three separate +3.3 V bias supplies (VCC1, VCC2, VCC3) routed with individual ultra-wideband decoupling (100 nF ATC545L104KW16T recommended). Each supply must ramp within 100 µs to ensure proper startup behavior and avoid latch-up.
What is the log video output voltage range and slope of the HMC813-SX?
The HMC813-SX log video output spans 0.9 V to 1.73 V over its full 55 dB input range, with a nominal slope of 15 mV/dB. This linear-in-dB transfer function enables direct interfacing with 12-bit+ ADCs without software compensation for amplitude scaling.
How is the enable (EN) pin used on the HMC813-SX?
The EN pin on the HMC813-SX is active-high: applying +3.3 V enables normal operation (153 mA supply current), while grounding it reduces current to <3 mA. This allows rapid power cycling in battery-constrained or thermally sensitive EW subsystems without reinitializing external circuitry.
Is the HMC813-SX pin-compatible with other Hittite SDLVAs like the HMC6012 or HMC1099?
No - the HMC813-SX uses a unique 24-lead 4×4 mm ceramic package with dedicated VCC1/VCC2/VCC3, EN, and dual RF I/O pins. Neither HMC6012 (16-lead) nor HMC1099LP4E (24-lead but different pinout and biasing) share pin compatibility; PCB redesign is required for substitution.
