Product details
Overview
HMC550E from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC single-pole single-throw (SPST) failsafe RF switch in SOT26 package, operating from DC to 6 GHz with 0.7 dB typical insertion loss, +52 dBm input IP3, and 200 nA on-state current. It serves as a low-power RF path controller in battery-operated RFID tags and ISM-band portable transceivers.
For engineers reviewing the HMC550E datasheet, HMC550E pinout, HMC550E application, or HMC550E equivalent, this page delivers verified electrical specs, failsafe control behavior, SOT26 terminal mapping, thermal limits, and real-world use cases in automotive telematics and WiMAX front-ends.
Technical Context
The HMC550E implements a monolithic GaAs MMIC topology with reflective-open "Off" state at both RF1 and RF2 ports, requiring external DC blocking capacitors. Its failsafe architecture ensures default "On" conduction (RF1–RF2 path closed) when Vdd and Vctl are unpowered.
It supports CMOS-compatible control voltages (Vctl = 0/+3.3 V), operates across 1.2–5 V Vdd, and maintains RF performance over −40°C to +85°C with 150°C/W thermal resistance. Switching speed is 40 ns rise/fall and 50 ns turn-on/turn-off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 6 GHz - enables IF and RF switching in RFID, WLAN, and automotive radar bands without band-specific redesign. |
| Insertion Loss | 0.7 dB typ. - minimizes signal attenuation in low-power portable transmit paths, preserving SNR in battery-constrained systems. |
| Input IP3 | +52 dBm - supports high-linearity operation with two-tone +17 dBm inputs, critical for multi-carrier ISM/WiMAX transmitters. |
| Isolation | 25 dB @ DC–2 GHz - suppresses leakage between RF paths in duplexed or TDD architectures where Tx/Rx isolation is essential. |
| On-State Current | 200 nA - enables ultra-low-quiescent-power operation, extending battery life in ETC tags and sensor nodes. |
| Switching Speed | 40 ns tRISE/tFALL - suitable for fast TDD frame switching in WiBro and LTE-U applications with tight timing margins. |
| Operating Temp | −40°C to +85°C - qualified for under-hood automotive telematics and industrial outdoor wireless modules. |
Pinout & Package
Package: RoHS-compliant SOT26 plastic package with 100% matte Sn lead finish, MSL1 rating, and max peak reflow temperature of 260 °C. All ground leads (Pins 2 and 5) must be soldered directly to PCB RF ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3 | RF1, RF2 | DC-coupled 50 Ω RF ports; require external DC blocking capacitors to prevent bias disruption and define low-frequency cutoff. |
| 2, 5 | GND | RF ground terminals; must connect directly to solid ground plane to maintain impedance integrity and minimize radiation loss. |
| 4 | Vdd | Supply voltage input (1.2–5 V); powers internal GaAs circuitry and sets maximum allowable Vctl swing per datasheet limits. |
| 6 | Vctl | Control voltage input; logic "High" (>1.8 V) disables RF path; unpowered or low state enables failsafe "On" conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Failsafe "On" at power loss | Ensures RF continuity during brownout or sleep mode-critical for safety-critical automotive telematics and emergency beacon links. |
| Ultra-low on-state current | 200 nA enables >10-year battery life in passive RFID tags and maintenance-free IoT sensors. |
| Wide Vdd compatibility | 1.2–5 V operation allows direct interface with Li-ion, coin-cell, and 3.3 V/5 V system rails without LDO overhead. |
| Reflective-open "Off" state | Eliminates need for shunt termination resistors, reducing BOM count and PCB area in compact portable RF front-ends. |
| CMOS logic compatibility | Vctl thresholds align with standard 3.3 V CMOS outputs, enabling direct drive from microcontrollers without level-shifting. |
Applications
| RFID Electronic Toll Collection (ETC) | ISM-Band Portable Transceivers |

IC Role / Device Role / Timing Role: RF path selector enabling dynamic antenna port assignment between two transmitters without external relays. Use Value: +52 dBm IP3 handles composite WiMAX signals up to 27 dBm P0.1dB; SOT26 footprint reduces board space vs. legacy SOIC switches. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST RF switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QM11036 | Higher frequency (DC–7 GHz), higher IP3 (+55 dBm), but requires external bias network and lacks failsafe "On" behavior. | Preferred for 5G NR sub-6 GHz base stations needing extended bandwidth and linearity; unsuitable where power-loss continuity is mandatory. | Select QM11036 only when failsafe operation is unnecessary and 7 GHz coverage is required. |
| Skyworks SKY13370-374LF | Lower insertion loss (0.45 dB), smaller 2×2 mm DFN package, but rated only to 4.2 GHz and consumes 1 µA on-state current. | Better for compact 2.4/5 GHz Wi-Fi 6 clients where size and loss dominate; not viable for 5.8 GHz WiBro or 6 GHz automotive radar. | Choose SKY13370-374LF for space-constrained 2.4–4.2 GHz designs prioritizing loss over failsafe reliability. |
Compared with QM11036 and SKY13370-374LF, the HMC550E uniquely combines failsafe "On" behavior, 6 GHz bandwidth, and sub-µA current draw-making it irreplaceable in battery-powered ETC tags and automotive GNSS modules where continuity and longevity are non-negotiable.

FAQ
What is the failsafe behavior of the HMC550E?
The HMC550E defaults to "On" (low insertion loss between RF1 and RF2) when Vdd and Vctl are unpowered. This failsafe state ensures RF continuity during power interruptions, making it ideal for automotive telematics and emergency RFID tags where signal loss could compromise functionality. The HMC550E achieves this via internal GaAs topology that conducts without applied bias.
Does the HMC550E require external DC blocking capacitors?
Yes, the HMC550E requires external DC blocking capacitors at both RF1 and RF2 pins because its RF ports are DC-coupled. These capacitors prevent DC bias from disrupting connected components and set the low-frequency cutoff-e.g., a 100 pF capacitor yields ~32 MHz lower limit. The HMC550E datasheet specifies this as mandatory for proper operation.
What is the maximum RF input power the HMC550E can handle?
The HMC550E supports +34 dBm absolute maximum RF input power under powered conditions (Vctl = 0/+3.3 V), and +35 dBm hot-switch power level. At typical operating conditions (Vdd = 3.3 V), its P0.1dB compression point is +23 to +27 dBm across 0.5–6 GHz. Exceeding these levels risks permanent GaAs degradation, so the HMC550E must be used within published limits.
Can the HMC550E operate from a 1.8 V supply?
Yes, the HMC550E supports Vdd from 1.2 V to 5 V, including 1.8 V. At 1.8 V, its control voltage thresholds scale accordingly: Vctl "Low" must be <0.4 V and "High" >0.8 V to ensure reliable switching. This flexibility allows direct integration with 1.8 V microcontrollers and low-voltage battery systems without level shifters-confirming the HMC550E's suitability for ultra-low-power designs.
How does the HMC550E compare to the HMC550 in terms of packaging and compliance?
The HMC550E uses RoHS-compliant low-stress injection-molded plastic with 100% matte Sn lead finish and MSL1 rating (260 °C peak reflow), whereas the HMC550 uses Sn/Pb solder and has a 235 °C reflow limit. Both share identical electrical specs and SOT26 footprint, but the HMC550E is required for lead-free manufacturing. The HMC550E marking "550E" distinguishes it on-package for traceability.
