Product details
Overview
118980-HMC612LP4 from Analog Devices (formerly Hittite Microwave) is a logarithmic detector/controller IC that converts RF/IF input signals from 50 Hz to 3 GHz into a proportional DC output voltage. It delivers up to 74 dB dynamic range, ±1 dB accuracy over 60 dB at ≤0.9 GHz, and operates from +2.7 V to +5.5 V supply. Its dual-mode operation supports RSSI in cellular base stations and AGC loops in WiMAX transceivers.
For engineers reviewing the 118980-HMC612LP4 datasheet, 118980-HMC612LP4 pinout, 118980-HMC612LP4 application, or 118980-HMC612LP4 equivalent, key selection criteria include logarithmic slope stability across frequency, temperature-compensated intercept drift, power-down enable timing, and RF input return loss performance up to 3 GHz.
Technical Context
The 118980-HMC612LP4 employs successive compression architecture with cascaded amplifiers saturating sequentially to approximate a true logarithmic transfer function. Its output is derived from summed square-law detector outputs, converted to voltage domain and buffered for LOGOUT drive capability.
In detector mode, LOGOUT (Pin 17) is shorted to VSET (Pin 18), yielding nominal 19 mV/dB slope and −99 dBm intercept. In controller mode, external voltage applied to VSET enables closed-loop AGC/APC with 30 kΩ input impedance and 0.6–1.9 V valid range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 50 Hz to 3000 MHz - supports low-frequency IF monitoring and full-band RF detection without external mixing. |
| Dynamic Range (±3 dB) | 74 dB at 1 GHz - enables accurate power measurement across multi-decade signal levels in receiver front-ends. |
| Logarithmic Slope | 19.7 mV/dB typical at 900 MHz - provides stable gain scaling for RSSI calibration with <±0.4 mV/dB variation from 100 MHz to 2.5 GHz. |
| Output Intercept | −94.5 dBm typical at 900 MHz - defines lower power limit where output remains linearly proportional to input log-power. |
| Supply Voltage | +2.7 V to +5.5 V - compatible with both 3.3 V and 5 V system rails without level-shifting. |
| Power-Down Current | 1 mA - reduces system standby power when PWD pin is driven >0.8×Vcc. |
| Operating Temperature | −45 °C to +85 °C - qualified for outdoor wireless infrastructure and industrial RF monitoring environments. |
Pinout & Package
118980-HMC612LP4 uses a 4×4 mm leadless surface-mount package (LP4) with exposed thermal paddle requiring RF/DC grounding. Pin count is 23, including 10 N/C pins tied to ground per design specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 6, 7–12, 15, 18–21 | N/C (grounded) | Internally unconnected but must be soldered to PCB ground plane for RF shielding and thermal conduction. |
| 2, 5 | Vcc1, Vcc2 | Dual bias supply inputs - both require local 0.1 μF decoupling to minimize supply noise coupling into RF path. |
| 3, 4 | INP, INN | Differential RF input - single-ended operation uses INP with INN AC-coupled to ground via 10 μF capacitor. |
| 13 | CLPF | Loop filter capacitor terminal - connects external capacitor to reduce LOGOUT ripple in AGC applications. |
| 14 | PWD | Power-down control - logic-high (>0.8×Vcc) disables internal circuitry, reducing current to 1 mA. |
| 16 | VSET | Controller reference input - accepts 0.6–1.9 V for AGC setpoint; shorted to LOGOUT in detector mode. |
| 17 | LOGOUT | Logarithmic DC output - delivers buffered voltage proportional to input power; drives up to 3 mA load. |
| 22, 23 | COFSB, COFSA | High-pass corner adjustment - external capacitors extend low-frequency response down to 50 Hz. |
| Package Base | GND | Exposed thermal paddle - must be soldered to solid ground plane with ≥6 thermal vias for Rth = 126 °C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Wideband logarithmic detection | Operates continuously from 50 Hz to 3 GHz without band switching or calibration reconfiguration. |
| Temperature-stable intercept | Drift of −11.7 mdBm/°C at −30 dBm input ensures RSSI accuracy remains within ±1.5 dB over full −45 °C to +85 °C range. |
| Fast output response | Rise/fall times of 19 ns / 100 ns at −15 dBm enable real-time power envelope tracking in burst-mode systems. |
| Dual operational modes | Hardware-selectable detector (LOGOUT↔VSET short) or controller (external VSET voltage) via simple PCB jumper or routing. |
| Low-power shutdown | Power-down mode draws only 1 mA while preserving state, enabling rapid wake-up (<4 μs) for duty-cycled RF monitoring. |

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 bandwidth (0.1–4.5 GHz), higher supply current (42 mA), no power-down mode. | Better suited for high-speed test equipment; lacks low-power sleep for battery-operated nodes. | Select when >4 GHz coverage or faster settling (<10 ns) is required; verify thermal management for 42 mA continuous draw. |
| HMC1093LP4E | Narrower bandwidth (10 MHz–8 GHz), lower dynamic range (65 dB), single 3.3 V supply only. | Optimized for microwave point-to-point links; not rated below 10 MHz. | Prefer for E-band backhaul where 8 GHz upper limit and compact layout outweigh low-frequency needs. |
Compared with ADL5513ACPZ-R7 and HMC1093LP4E, the 118980-HMC612LP4 uniquely balances ultra-low-frequency support (50 Hz), integrated power-down, and 74 dB dynamic range - making it optimal for wideband infrastructure monitoring where duty cycling and IF/RF coexistence matter.

FAQ
What is the minimum detectable input frequency for the 118980-HMC612LP4?
The 118980-HMC612LP4 supports input frequencies as low as 50 Hz, enabled by external capacitors on COFSB and COFSA pins. This allows use in IF stages with very low intermediate frequencies and baseband power monitoring applications where traditional RF detectors fail.
How does the 118980-HMC612LP4 achieve ±1 dB accuracy over 60 dB dynamic range?
The 118980-HMC612LP4 achieves ±1 dB accuracy through successive compression architecture: multiple amplifier stages saturate progressively, summing their square-law outputs to synthesize a highly linear logarithmic transfer function-verified at 900 MHz and maintained up to 0.9 GHz.
Can the 118980-HMC612LP4 operate in both detector and controller modes simultaneously?
No-the 118980-HMC612LP4 operates in either detector mode (LOGOUT shorted to VSET) or controller mode (external voltage applied to VSET), selected at board level. Simultaneous operation is not supported; mode selection requires physical connection change or switch-controlled routing.
What is the recommended PCB layout practice for the exposed paddle of the 118980-HMC612LP4?
The exposed paddle of the 118980-HMC612LP4 must be soldered to a solid RF/DC ground plane using ≥6 thermal vias (0.3 mm diameter, 0.8 mm pitch). Per Hittite Application Note, this ensures thermal resistance of 126 °C/W and prevents RF leakage through unterminated paddle edges.
Does the 118980-HMC612LP4 require external calibration for temperature drift compensation?
No-temperature drift is internally compensated; the 118980-HMC612LP4 exhibits only −11.7 mdBm/°C intercept drift from −45 °C to +85 °C. System-level calibration is optional and typically limited to one-point offset trim at room temperature for highest accuracy.
