Product details
Overview
HMC713MS8 from Analog Devices (formerly Hittite Microwave) is a logarithmic RF detector/controller IC operating from 45 MHz to 2700 MHz, delivering 54 dB dynamic range with ±1 dB accuracy up to 2.7 GHz, 17 mV/dB slope, and -68 dBm intercept - used for RSSI, AGC, and power monitoring in cellular infrastructure and radar front-ends.
For engineers reviewing the HMC713MS8 datasheet, HMC713MS8 pinout, HMC713MS8 application, or HMC713MS8 equivalent, key selection criteria include its dual-mode operation (detector/controller), temperature-stable logarithmic response across -40°C to +85°C, fast 24 ns rise time, MSOP-8 package compatibility, and low-power 0.3 mA shutdown current.
Technical Context
The HMC713MS8 employs successive compression architecture: cascaded amplifiers saturate progressively to generate a highly linear logarithmic transfer function over 54 dB input range. Its dual outputs - OUT (logarithmic) and OUTN (inverted, OUTN = 2.55 − 2 × OUT) - support differential measurement and noise rejection.
It operates in two distinct modes: detector mode (OUT shorted to VSET via RC network, yielding 17 mV/dB slope) and controller mode (external voltage applied to VSET to close AGC/APC loops). Power-down is controlled by EN pin with 0.2×Vcc threshold, reducing supply current from 17 mA to 0.3 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 45 MHz to 2700 MHz - supports LTE Band 1–40, WiMAX, and S-band radar signal detection. |
| Dynamic Range (±1 dB) | 54 dB at 900/1900/2200 MHz - enables accurate power measurement across multi-decade RF input levels. |
| Logarithmic Slope | 17.2 mV/dB typical at 2.7 GHz - provides stable gain-per-dB scaling for precise RSSI calibration. |
| Intercept Point | -68 dBm typical at 45 MHz - defines lower limit of usable log-linear region; shifts ≤2 dB across frequency. |
| Supply Voltage | +2.7 V to +5.5 V - compatible with 3.3 V and 5 V system rails without level-shifting. |
| Rise/Fall Time | 24 ns / 70 ns - supports real-time RF envelope tracking in burst-mode transceivers. |
| Power-Down Current | 0.3 mA - reduces idle power in battery-sensitive or duty-cycled systems. |
Pinout & Package
MSOP-8 surface-mount package (14.8 mm² footprint), exposed paddle thermally connected to PCB ground per datasheet layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 INP | RF Input | 50 Ω single-ended RF port; requires impedance-matched trace and DC blocking if needed. |
| 2 EN | Enable Control | Logic-level input: >0.8×Vcc enables device; <0.2×Vcc places IC in 0.3 mA shutdown state. |
| 3 VSET | Setpoint Reference | In controller mode: external voltage sets target output power; in detector mode: tied to OUT for closed-loop log conversion. |
| 4 CLPF | Low-Pass Filter Node | Connects external capacitor (e.g., 10 nF) to reduce output ripple and improve video bandwidth stability. |
| 5 GND | Ground Reference | Primary analog ground; must be low-inductance connection to PCB ground plane. |
| 6 OUT | Logarithmic Output | DC voltage proportional to input RF power; 0.2–1.2 V range in closed-loop detector mode. |
| 7 OUTN | Inverted Log Output | Differential complement: OUTN = 2.55 − 2 × OUT - enables noise-cancelling readout or comparator use. |
| 8 Vcc | Supply Rail | +2.7 V to +5.5 V bias; requires local 0.1 µF ceramic decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Successive compression architecture | Delivers true logarithmic response with ±1 dB linearity over 54 dB without external calibration. |
| Dual-mode operation | Configurable as detector (RSSI) or controller (AGC/APC) via simple external connections - no firmware or digital interface required. |
| Temperature-stable performance | Output error variation ≤0.8 dB from -40°C to +85°C at -20 dBm input - eliminates need for thermal compensation circuitry. |
| Fast envelope response | 24 ns rise time enables tracking of LTE TDD bursts and pulsed radar signals without distortion. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar logarithmic detector/controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADL5513ACPZ-R7 | Wider 100 MHz–4 GHz range; 65 dB dynamic range; requires 5 V supply only; no OUTN output. | Better suited for 4G/5G mmWave front-ends above 3 GHz; lacks differential output for noise-sensitive environments. | Select ADL5513 when operating >2.7 GHz or requiring >60 dB range; avoid if dual-output or 3.3 V operation is mandatory. |
| LT5537EMS8#TRPBF | Narrower 1 MHz–1 GHz range; 45 dB dynamic range; integrated temperature compensation; 3.3 V only. | Optimized for IF-stage power monitoring in legacy wireless infrastructure; lower frequency ceiling limits LTE band coverage. | Select LT5537 for cost-sensitive, narrowband IF detection below 1 GHz where temperature drift must be minimized. |
Compared with ADL5513ACPZ-R7 and LT5537EMS8#TRPBF, the HMC713MS8 offers balanced 45 MHz–2700 MHz coverage, true differential output (OUT/OUTN), and dual-voltage operation - making it optimal for mid-band cellular, radar, and mixed-signal AGC designs where layout space and supply flexibility matter.

FAQ
What is the operating frequency range of the HMC713MS8?
The HMC713MS8 operates from 45 MHz to 2700 MHz. This range covers all major cellular bands (including LTE Bands 1–40), WiMAX, and S-band radar frequencies. Performance specifications such as ±1 dB dynamic range and 17 mV/dB slope are validated across this full span, with data provided at 45, 100, 900, 1900, 2200, and 2700 MHz points in the official datasheet.
How does the HMC713MS8 support both detector and controller modes?
The HMC713MS8 supports detector mode by connecting OUT to VSET through an RC network - producing a logarithmic DC output proportional to RF input power. In controller mode, an external voltage is applied to VSET to establish a target power level, and the OUT/OUTN outputs drive a VGA or attenuator to maintain that setpoint. The HMC713MS8 requires no digital configuration - mode selection is purely analog and hardware-defined.
What is the significance of the OUTN pin on the HMC713MS8?
The OUTN pin on the HMC713MS8 provides an inverted logarithmic output defined as OUTN = 2.55 − 2 × OUT. This enables differential measurement to reject common-mode noise, improves ADC resolution when used with differential inputs, and supports comparator-based threshold detection without additional op-amps. Its 0.2–2.1 V output range is fully specified and characterized across temperature.
Does the HMC713MS8 require external components for basic operation?
Yes - the HMC713MS8 requires external components for stable operation: a 0.1 µF ceramic capacitor on Vcc, a DC-blocking capacitor on INP (if AC-coupled), and a resistor-capacitor network between OUT and VSET for detector mode. For controller mode, R6 and C3 are removed from the evaluation board layout and replaced with a 1 kΩ resistor and 100 pF capacitor per the application schematic. These are not optional; they define loop stability and DC operating point.
What is the power-down behavior of the HMC713MS8?
When the EN pin voltage falls below 0.2 × Vcc, the HMC713MS8 enters power-down mode, reducing supply current from 17 mA to 0.3 mA while maintaining pin states. The device retains its analog characteristics and resumes full operation within nanoseconds upon EN reactivation. This feature is explicitly characterized in the datasheet under "Power Down (EN) Interface" with defined voltage thresholds and timing.
