Product details
Overview
HMC813LC4B from Analog Devices (formerly Hittite Microwave) is a Successive Detection Log Video Amplifier (SDLVA) designed for RF power measurement and logarithmic signal conditioning in wideband receiver front-ends. 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 provides 15 mV/dB log video output slope - ideal for EW/ELINT channelized receivers requiring fast, accurate amplitude detection.
For engineers reviewing the HMC813LC4B datasheet, HMC813LC4B pinout, HMC813LC4B application, or HMC813LC4B equivalent, key selection criteria include its 1–20 GHz input bandwidth, single +3.3 V supply operation, 153 mA supply current, 4×4 mm ceramic SMT package, and −53 to +7 dBm dynamic input range with ±0.5 dB log linearity over temperature (−55 to +85 °C).
Technical Context
The HMC813LC4B implements a multi-stage successive detection architecture to convert RF input amplitude into a linear-in-dB video output voltage. Its internal gain stages are cascaded with detector cells and summing networks to achieve flat frequency response (±1.5 dB) and low recovery time (<15 ns) across 1–20 GHz.
It supports single-ended RF operation via AC-coupled differential ports (RFINP/RFINN, RFOUTP/RFOUTN), uses four independent bias supplies (VCC1–VCC3, EN), and requires ≥1 kΩ load on the VIDEO OUT pin. The enable pin (EN) reduces supply current to <3 mA in standby mode, supporting power-gated system architectures.

Equivalent & Alternatives
The following parts are listed as comparable options for similar logarithmic detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1099LP4E | Wider 0.1–26.5 GHz range; 60 dB logging range; higher 200 mA supply current; 5×5 mm package. | Supports lower-frequency SIGINT and higher-frequency millimeter-wave test; less suitable for space-constrained 4×4 mm layouts. | Select HMC1099LP4E when extended low-end coverage or higher dynamic range is required; verify PCB footprint and thermal margin. |
| LT5537IMS#TRPBF | DC–1 GHz range; 60 dB range; 3.3 V supply; 10 mA current; 10-lead MSOP package. | Targeted at IF/baseband and sub-1 GHz wireless infrastructure; not viable for 1–20 GHz RF front-end use. | Choose LT5537IMS#TRPBF only for low-frequency power monitoring; HMC813LC4B remains mandatory for microwave-band SDLVA functionality. |

FAQ
What is the operating frequency range of the HMC813LC4B?
The HMC813LC4B operates from 1 to 20 GHz with specified performance including ±1.5 dB frequency flatness and ±1 dB log linearity across this full band. All electrical specifications - such as logging range, rise/fall time, and output slope - are validated within this range under standard conditions (TA = +25 °C, Vcc = +3.3 V).
Does the HMC813LC4B require dual or differential power supplies?
No, the HMC813LC4B operates from a single +3.3 V supply across all bias rails (VCC1, VCC2, VCC3). However, these rails must be independently filtered using ultra-wideband capacitors (e.g., 100 nF ATC545L104KW16T) to prevent inter-stage noise coupling and ensure stable startup with <100 µs rise time.
What is the purpose of the limited RF output on the HMC813LC4B?
The limited RF output (−7 dBm saturated power, 18 dB return loss) on the HMC813LC4B provides a pass-through signal for downstream monitoring or mixing without requiring external buffering. It is not intended for driving loads directly but enables system-level signal routing while maintaining isolation between input and output paths.
How does the HMC813LC4B handle temperature variation in log linearity?
The HMC813LC4B maintains ±0.5 dB log linearity over temperature (−55 to +85 °C) at 10 GHz with −20 dBm input, and its log video output slope varies only 10 µV/dB°C. This tight thermal stability eliminates need for per-temperature calibration in deployed military systems operating across extreme environmental conditions.
Can the HMC813LC4B be used in DC-coupled configurations?
No - the HMC813LC4B requires AC-coupled RF inputs and outputs. RFINN and RFOUTN must be AC-coupled to ground via 50 Ω for single-ended operation, and the VIDEO OUT pin expects a ≥1 kΩ resistive load. DC coupling would violate absolute maximum ratings and degrade log accuracy due to internal bias dependencies.
