Product details
Overview
HMC333E from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC single-balanced mixer IC with integrated LO amplifier, operating from 3.0 to 3.8 GHz as upconverter or downconverter. It delivers 8.5 dB typical conversion loss, +10 dBm input IP3, and requires only 0 dBm LO drive at 3 V supply - enabling compact RF front-ends in wireless infrastructure.
For engineers reviewing the HMC333E datasheet, HMC333E pinout, HMC333E application, or HMC333E equivalent, this page provides verified specifications, package details, real-world use scenarios, and validated alternative options for 3–3.8 GHz RF transceiver design.
Technical Context
The HMC333E integrates a broadband GaAs LO amplifier directly coupled to a single-balanced passive mixer core, eliminating external LO buffering. Its DC-coupled IF port supports baseband and low-IF architectures, while RF and LO ports are AC-coupled and 50 Ω matched across 3.0–3.8 GHz.
It operates from a single +3V to +5V supply, drawing only 7 mA; thermal design accommodates −40°C to +85°C operation with 238 mW max dissipation at 85°C. Absolute maximum RF/LO input is +13 dBm, and IF DC current must remain within ±3 mA to prevent damage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range (RF/LO) | 3.0–3.8 GHz - defines usable band for cellular, WLL, and point-to-point radio links |
| Conversion Loss | 8.5 dB typical - sets minimum gain budget required in preceding LNA and following IF amplifier stages |
| Input IP3 | +10 dBm at 3.5 GHz - determines two-tone linearity headroom before third-order distortion dominates |
| LO Drive Level | 0 dBm - eliminates need for external LO buffer amplifier, reducing BOM count and layout complexity |
| Supply Current | 7 mA at +3 V - enables low-power portable and battery-assisted RF modules |
| Noise Figure (SSB) | 8.5 dB typical - impacts overall receiver sensitivity when used as downconverter |
| LO–RF Isolation | 10–15 dB - limits LO leakage into antenna path, easing filtering requirements in transmit chains |
Pinout & Package
HMC333E uses a RoHS-compliant low-stress injection-molded plastic SMT package with matte tin lead finish (MSL1, 260°C peak reflow). All ground leads (Pins 2 and 5) must be soldered directly to PCB RF ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vdd | Power supply for integrated LO amplifier; requires 10 pF + 10,000 pF bypass caps and 1.8 nH RF choke |
| 2, 5 | GND | RF ground reference; must connect to solid ground plane via multiple vias to minimize inductance |
| 3 | IF | DC-coupled output/input port; limited to ±3 mA DC current to avoid die damage |
| 4 | RF | AC-coupled, 50 Ω matched RF port (3.0–3.8 GHz); no external matching needed |
| 6 | LO | AC-coupled, 50 Ω matched LO port (3.0–3.8 GHz); accepts 0 dBm drive without external amp |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LO amplifier | Reduces external component count by eliminating discrete LO buffer; consumes <25 mW |
| Single positive supply | Operates from +3V to +5V - compatible with standard logic rails and simplifies power sequencing |
| DC-coupled IF port | Supports zero-IF and low-IF architectures without blocking capacitors; enables I/Q demodulator integration |
| High linearity | +10 dBm input IP3 ensures robust performance in multi-carrier and high-dynamic-range environments |
| Compact SMT footprint | Enables dense RF layout in space-constrained mmWave and small-cell base station modules |
Applications
| Wireless Local Loop (WLL) | Point-to-Point Radio |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC333 | Same die, Sn/Pb lead finish, MSL1 rated for 235°C peak reflow; no RoHS compliance | Legacy industrial systems requiring Pb-based soldering; not suitable for new RoHS-compliant designs | Select HMC333 only if manufacturing process mandates Sn/Pb assembly and Pb exemption applies |
| ADL5801ACPZ-R7 | SiGe active double-balanced mixer; 2.3–3.8 GHz RF, 50–1000 MHz IF, 9.5 dB conversion gain, +24 dBm IIP3 | Higher dynamic range and gain; requires −5 V and +5 V dual supplies; larger 24-lead LFCSP | Choose ADL5801ACPZ-R7 when system needs >+15 dBm IIP3 and can accommodate dual supply and larger footprint |
Compared with HMC333E, HMC333 offers identical RF performance but lacks RoHS compliance, while ADL5801ACPZ-R7 trades lower power and smaller size for significantly higher linearity and gain - making it suitable for test equipment but over-specified for cost-sensitive WLL nodes.

FAQ
What is the absolute maximum RF input power rating for the HMC333E?
The HMC333E has an absolute maximum RF input power rating of +13 dBm at Vdd = +3 V. Exceeding this level risks permanent damage to the mixer diodes or integrated LO amplifier. This rating applies regardless of whether the device is used as an upconverter or downconverter, and must be enforced with appropriate front-end limiting or attenuation in high-power transmit paths.
Can the HMC333E operate with a 5 V supply voltage?
Yes, the HMC333E supports a single positive supply from +3 V to +5 V. At +5 V, supply current increases slightly but remains within safe dissipation limits; however, conversion loss and IP3 are characterized at +3 V, so full performance validation is recommended at the intended operating voltage. The absolute maximum Vdd is 5.5 V.
Is the IF port of the HMC333E truly DC-coupled, and what are the design constraints?
Yes, the IF port (Pin 3) of the HMC333E is DC-coupled, enabling zero-IF architectures. However, it must not source or sink more than ±3 mA DC current - exceeding this causes non-function and possible die failure. External DC blocking is required only if the application does not require DC response.
Does the HMC333E require external matching networks on RF or LO ports?
No, the RF (Pin 4) and LO (Pin 6) ports of the HMC333E are internally matched to 50 Ω across 3.0–3.8 GHz. No external matching components are needed, though proper RF layout - including controlled-impedance traces and grounding - remains critical to maintain specified isolation and conversion loss.
What is the thermal derating behavior of the HMC333E above 85°C ambient?
The HMC333E has a continuous power dissipation limit of 238 mW at Ta = +85°C, with linear derating of 2.64 mW/°C above that temperature. At +105°C ambient, maximum allowable dissipation drops to 185 mW. Thermal vias and copper pour under the package are strongly recommended to sustain reliable operation near upper temperature limits.
