Product details
Overview
HMC333ETR 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-enabling compact wireless local loop transceivers.
For engineers reviewing the HMC333ETR datasheet, HMC333ETR pinout, HMC333ETR application, or HMC333ETR equivalent, key selection criteria include its integrated LO amplifier enabling low-drive operation, 3.0–3.8 GHz RF/LO bandwidth, DC–1.0 GHz IF support, 8.5 dB conversion loss, and RoHS-compliant SMT package with MSL1 rating.
Technical Context
The HMC333ETR implements a single-balanced passive diode-ring mixer core with monolithically integrated GaAs LO amplifier, eliminating external driver 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 current limit.
Operation is validated for both upconversion and downconversion modes at IF = 100 MHz, with specified performance including LO-to-RF isolation ≥10 dB, LO-to-IF isolation ≥5 dB, and RF-to-IF isolation ≥10 dB-all measured at +25°C with 0 dBm LO drive and +3V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 3.0–3.8 GHz: Full-band 50 Ω match enables direct integration into 3.3/3.5/3.7 GHz wireless infrastructure front-ends without external matching. |
| IF Bandwidth | DC–1.0 GHz: Supports baseband I/Q, low-IF, and zero-IF architectures with DC coupling capability (≤±3 mA IF current). |
| Conversion Loss | 8.5 dB typ (max 11 dB): Defines signal attenuation from RF to IF path; impacts receiver noise figure and transmitter output power efficiency. |
| Input IP3 | +10 dBm typ: Indicates linearity under two-tone conditions (−10 dBm/tone, 1 MHz spacing); critical for adjacent-channel interference rejection. |
| LO Drive Level | 0 dBm: Integrated LO amplifier reduces system-level LO source requirement-eliminates need for external driver stage. |
| Supply Current | 7 mA @ +3V: Enables ultra-low-power operation in battery-backed or thermally constrained RF modules. |
| Noise Figure (SSB) | 8.5 dB typ: Directly impacts receiver sensitivity; matches conversion loss due to passive mixer topology with active LO amplification. |
Pinout & Package
Package: 6-lead SMT low-stress injection-molded plastic (RoHS-compliant), matte Sn lead finish, MSL1 rated (260°C peak reflow), outline per datasheet page 9-198.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Vdd | LO amplifier power supply: Requires dual bypass (10 pF + 10,000 pF) and 1.8 nH RF choke for stable bias and LO amplification. |
| 2, 5 | GND | RF ground reference: Both pins must be soldered directly to PCB RF ground plane to maintain port match and isolation. |
| 3 | IF | DC-coupled IF output/input: Supports DC–1.0 GHz; must not exceed ±3 mA current to prevent die damage. |
| 4 | RF | AC-coupled RF port: Internally matched to 50 Ω across 3.0–3.8 GHz; no external matching required. |
| 6 | LO | AC-coupled LO input: Internally matched to 50 Ω across 3.0–3.8 GHz; accepts 0 dBm drive for full performance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LO amplifier | Reduces system LO drive requirement to 0 dBm-enables direct interface with low-power synthesizers or VCOs. |
| Single positive supply | Operates from +3V to +5V: Simplifies power architecture and supports compatibility with common digital supply rails. |
| DC-coupled IF port | Enables true zero-IF and complex I/Q demodulation without blocking capacitors-critical for direct-conversion receivers. |
| High LO-to-RF isolation | ≥10 dB min: Minimizes LO leakage into antenna path-reduces spurious emissions and improves transmit spectral purity. |
| MSL1 RoHS package | 260°C peak reflow compatible: Ensures robust manufacturability in lead-free SMT assembly lines without moisture sensitivity risk. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC333TR | Sn/Pb lead finish, non-RoHS, MSL1 (235°C peak reflow); identical electrical specs and pinout. | Legacy industrial systems requiring Pb-based solder compatibility or exempt from RoHS compliance. | Select HMC333TR only when Pb-based assembly process is mandated and RoHS exemption applies. |
| Qorvo QM11036 | Wider RF range (2.3–4.2 GHz), higher IP3 (+13 dBm), but requires −1 dBm LO drive and 10 mA supply current. | Systems needing extended frequency coverage or improved linearity at cost of higher LO drive and power. | Choose QM11036 when 3.0–3.8 GHz operation is insufficient or +13 dBm IP3 is required for dense multi-carrier environments. |
Compared with HMC333ETR, HMC333TR offers identical RF performance but lacks RoHS compliance, while QM11036 extends bandwidth and linearity at the expense of higher LO drive and current-making HMC333ETR optimal for cost-sensitive, RoHS-compliant 3.5 GHz WLL designs.

FAQ
What is the absolute maximum RF input power for the HMC333ETR?
The HMC333ETR has an absolute maximum RF input power rating of +13 dBm at Vdd = +3V. Exceeding this level risks permanent damage to the mixer diodes or LO amplifier. Operation above +1 dBm input power also degrades linearity-designers should limit RF input to ≤0 dBm for optimal IP3 and P1dB performance per datasheet characterization.
Does the HMC333ETR support zero-IF operation?
Yes, the HMC333ETR supports true zero-IF operation because its IF port is DC-coupled and functional from DC to 1.0 GHz. However, the IF pin must not source or sink more than ±3 mA of DC current-external DC blocking is required if the connected baseband circuit violates this current limit.
What external components are mandatory for HMC333ETR biasing?
Mandatory external components for HMC333ETR operation include two RF bypass capacitors (10 pF and 10,000 pF) and one RF choke (1.8 nH inductor) on Pin 1 (Vdd). Pins 2 and 5 must be soldered directly to RF ground. No external matching is needed on RF, LO, or IF ports due to internal 50 Ω matching.
Is the HMC333ETR pin-compatible with the HMC333TR?
Yes, the HMC333ETR is pin-compatible with the HMC333TR-both share identical 6-lead SMT footprint, pin numbering, and electrical interface. The only differences are RoHS compliance (matte Sn vs. Sn/Pb) and MSL1 reflow profile (260°C vs. 235°C), making them drop-in replacements in layout-constrained designs where material compliance permits.
What is the typical LO-to-RF isolation of the HMC333ETR at 3.5 GHz?
The typical LO-to-RF isolation of the HMC333ETR at 3.5 GHz is 12.5 dB, with a minimum guaranteed value of 10 dB across the full 3.0–3.8 GHz band at +25°C and 0 dBm LO drive. This isolation level helps suppress LO leakage into the antenna path, improving spectral purity in transmit applications.
