Product details
Overview
HMC333TR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC single-balanced mixer IC with integrated LO amplifier, operating as upconverter or downconverter in 3.0–3.8 GHz RF/LO band and DC–1.0 GHz IF band. It delivers 8.5 dB typical conversion loss, +10 dBm input IP3, and requires only 0 dBm LO drive at 7 mA from a +3V supply. Used in wireless local loop transceivers requiring low-power, high-linearity frequency translation.
For engineers reviewing the HMC333TR datasheet, HMC333TR pinout, HMC333TR application, or HMC333TR equivalent, key selection criteria include its integrated LO amplifier enabling minimal external drive, 3.0–3.8 GHz RF/LO bandwidth, DC–1.0 GHz IF support, 8.5 dB conversion loss, and +10 dBm input IP3 at 3.5 GHz - all critical for compact, low-power microwave transceiver design.
Technical Context
The HMC333TR implements a single-balanced passive diode ring mixer core with monolithically integrated GaAs LO amplifier, eliminating need for external LO buffer stages. Its RF and LO ports are AC-coupled and 50 Ω matched across 3.0–3.8 GHz, while the IF port is DC-coupled with ±3 mA absolute max current rating.
Operation supports both upconversion and downconversion modes with fixed 100 MHz IF reference point in characterization; isolation specs (LO–RF ≥10 dB, LO–IF ≥5 dB, RF–IF ≥10 dB) reflect balanced topology performance under +3V/0 dBm LO bias conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 3.0–3.8 GHz: Full operational band for signal translation without external tuning. |
| IF Frequency Range | DC–1.0 GHz: Supports baseband through L-band IF interfaces, including zero-IF architectures. |
| Conversion Loss | 8.5 dB typ: Directly impacts system noise figure and gain budget; measured at 3.5 GHz, IF = 100 MHz, LO = 0 dBm. |
| Input IP3 | +10 dBm typ: Enables handling of moderate interferers in dense RF environments like WLL base stations. |
| LO Drive Level | 0 dBm: Eliminates need for LO driver stage, reducing BOM count and power consumption. |
| Supply Current | 7 mA @ +3V: Enables ultra-low-power operation suitable for battery-assisted or thermally constrained modules. |
| LO–RF Isolation | ≥10 dB: Limits LO leakage into antenna path, easing filter requirements in transmit chains. |
Pinout & Package
HMC333TR uses a 6-lead SMT package with low-stress injection-molded plastic body, Sn/Pb lead finish, and MSL1 rating. All ground leads (Pins 2 & 5) must be soldered directly to PCB RF ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vdd | LO amplifier power rail; requires dual bypass (10 pF + 10,000 pF) and 1.8 nH RF choke for stable biasing. |
| 2, 5 | GND | RF ground reference; mandatory connection to solid ground plane to maintain port match and isolation. |
| 3 | IF | DC-coupled differential IF output/input; limited to ±3 mA DC current to prevent die damage. |
| 4 | RF | AC-coupled 50 Ω RF port; matched across full 3.0–3.8 GHz band for direct antenna or filter interface. |
| 6 | LO | AC-coupled 50 Ω LO input; accepts 0 dBm drive without external amplification. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LO amplifier | Reduces external component count by eliminating discrete LO buffer; enables 0 dBm drive requirement. |
| Single positive supply | Operates from +3V to +5V rail, simplifying power architecture versus dual-supply mixers. |
| DC-coupled IF port | Supports zero-IF and complex I/Q architectures without blocking capacitors or DC restoration circuits. |
| High linearity | +10 dBm input IP3 ensures robust operation in multi-carrier WLL and point-to-point radio systems. |
| Thermal stability | Specified over –40°C to +85°C ambient; maintains conversion loss and IP3 within 1.5 dB variation across range. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC333E | RoHS-compliant variant with matte tin lead finish and 260 °C reflow rating; identical electrical specs. | Required for lead-free manufacturing; same RF performance and pinout as HMC333TR. | Select HMC333E when RoHS compliance and Pb-free assembly are mandatory. |
| Qorvo QM11036 | Wider RF band (2.3–4.2 GHz), higher IP3 (+13 dBm), but requires +7 dBm LO drive and 12 mA supply current. | Better suited for wideband infrastructure where LO power is available; not drop-in due to LO drive and bias differences. | Choose QM11036 only if wider bandwidth and higher linearity outweigh increased LO drive and power overhead. |
Compared with HMC333E, the HMC333TR offers identical RF performance with Sn/Pb finish for legacy assembly, while QM11036 trades LO drive simplicity for broader bandwidth and higher linearity - making HMC333TR optimal for cost- and power-sensitive 3.0–3.8 GHz WLL designs.

FAQ
What is the recommended LO drive level for HMC333TR?
The HMC333TR requires only 0 dBm LO drive level across its 3.0–3.8 GHz band, enabled by its monolithically integrated LO amplifier. This eliminates the need for an external LO buffer stage, reducing system power consumption and component count. Operating outside this drive range may degrade conversion loss, IP3, or isolation performance - always verify with the HMC333TR datasheet's LO drive vs. conversion gain curves.
Can HMC333TR operate in zero-IF mode?
Yes, the HMC333TR supports zero-IF operation because its IF port is DC-coupled and specified from DC to 1.0 GHz. However, the IF pin must not source or sink more than ±3 mA DC current to avoid device malfunction or permanent damage. External DC blocking is required only when DC coupling is undesirable; otherwise, direct connection to baseband processing circuitry is valid for I/Q demodulation.
What is the package type and thermal rating of HMC333TR?
The HMC333TR uses a 6-lead surface-mount package with low-stress injection-molded plastic body, Sn/Pb lead finish, and MSL1 moisture sensitivity level. Its absolute maximum continuous power dissipation is 238 mW at +85 °C ambient, derating linearly at 2.64 mW/°C above that temperature. The operating junction temperature range is –40 °C to +125 °C, consistent with its –40 °C to +85 °C ambient rating.
How does HMC333TR compare to HMC333E?
The HMC333TR and HMC333E share identical electrical specifications, pinout, and RF performance. The primary difference is environmental compliance: HMC333TR uses Sn/Pb lead finish with 235 °C max reflow, while HMC333E is RoHS-compliant with 100% matte tin and 260 °C reflow capability. Both are functionally interchangeable in circuit design, but HMC333E is required for lead-free manufacturing processes.
What external components are required for HMC333TR biasing?
HMC333TR requires three external bias components on Pin 1 (Vdd): a 1.8 nH RF choke in series, plus two parallel bypass capacitors - 10 pF (high-frequency) and 10,000 pF (low-frequency). Pins 2 and 5 must connect directly to a low-inductance RF ground plane. No external matching is needed on RF, LO, or IF ports, as all are internally matched to 50 Ω (RF/LO) or DC-coupled (IF).
