Product details
Overview
HMC218MS8 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced mixer in an 8-lead MSOP package, operating from 4.5–6.0 GHz RF/LO and DC–1.6 GHz IF. It delivers 6.5 dB typical conversion loss, +18 dBm input IP3 at 5.2 GHz, and 30 dB LO/RF isolation, enabling high-linearity upconversion and downconversion in WiMAX and fixed wireless base stations.
For engineers reviewing the HMC218MS8 datasheet, HMC218MS8 pinout, HMC218MS8 application, or HMC218MS8 equivalent, this passive mixer requires no DC bias, supports wide IF bandwidth (DC–1.6 GHz), offers temperature-stable P1dB (4–10 dBm range), and integrates planar transformer baluns for balanced port operation without external hybrids.
Technical Context
This passive double-balanced mixer uses GaAs Schottky diodes and monolithic planar transformer baluns to achieve inherent LO-RF and LO-IF isolation without external filtering. Its topology eliminates even-order distortion and suppresses LO feedthrough across the full 4.5–6.0 GHz band.
Performance is specified across LO drive levels (+7 to +13 dBm) and temperature (−40°C to +85°C), with conversion loss varying from 6.5 dB (typ.) at +13 dBm LO to 9.5 dB (max.) at +7 dBm LO, and input IP3 ranging from +12 dBm (min.) to +18 dBm (typ.) at 5.2 GHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 4.5–6.0 GHz - Supports full-band operation in 5 GHz unlicensed and licensed wireless infrastructure. |
| IF Bandwidth | DC–1.6 GHz - Enables direct baseband-to-IF and wideband IF sampling without external IF transformers. |
| Conversion Loss | 6.5 dB (typ.) @ +13 dBm LO - Low signal attenuation preserves receiver sensitivity and reduces Tx chain gain requirements. |
| Input IP3 | +18 dBm (typ.) @ 5.2 GHz - High linearity prevents intermodulation distortion in dense multi-carrier environments. |
| LO–RF Isolation | 30 dB (typ.) - Minimizes LO leakage into antenna paths, easing front-end filter design and reducing radiated emissions. |
| Operating Temp. | −40°C to +85°C - Qualified for outdoor base station and industrial wireless equipment deployment. |
| Package | 8-lead MSOP (3.0 × 3.0 × 0.85 mm) - Surface-mount compatible with standard reflow profiles (MSL1, 260°C peak). |
Pinout & Package
The HMC218MS8 is housed in an RoHS-compliant, low-stress injection-molded plastic MSOP package with copper alloy leadframe and 100% matte tin plating. All ground leads (pins 1, 2, 7, 8) must be soldered directly to PCB RF ground per layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 7, 8 | Ground | RF and DC return paths; require low-inductance connection to solid ground plane via multiple vias. |
| 3 | RF Input | Differential RF port; matched to 50 Ω; accepts 4.5–6.0 GHz signals without external matching. |
| 4 | IF Output | Single-ended IF output; DC–1.6 GHz bandwidth; referenced to ground pins 1/2/7/8. |
| 5 | LO Input | Differential LO port; requires +7 to +13 dBm drive; internal balun enables single-ended LO drive with external 180° hybrid. |
| 6 | RF/IF Common | Center-tap node for internal transformer baluns; must be AC-grounded or DC-biased per application circuit. |
Key Features
| Feature | Design Value |
|---|---|
| No DC bias required | Passive operation eliminates bias network complexity, power supply dependencies, and thermal drift concerns. |
| Integrated planar transformer baluns | On-chip baluns replace discrete hybrid couplers, reducing board area and insertion loss in both LO and RF paths. |
| High LO–RF isolation (30 dB typ.) | Reduces need for external LO suppression filters, simplifying front-end architecture in frequency-agile transceivers. |
| Wide IF bandwidth (DC–1.6 GHz) | Supports zero-IF, low-IF, and complex IF architectures without IF transformer redesign or bandwidth limiting components. |
| Temperature-stable IP3 and P1dB | Input IP3 varies only ±3 dB over −40°C to +85°C, ensuring consistent linearity across environmental extremes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP3E | Wider RF/LO range (3.5–7.0 GHz), higher conversion loss (7.5 dB typ.), larger 16-pin LCC package. | Better suited for multi-band test equipment; less optimal for space-constrained 5 GHz fixed wireless designs. | Choose HMC1048LP3E when broader frequency coverage outweighs size and loss trade-offs. |
| Qorvo QM11036 | Similar 4.5–6.0 GHz range but +15 dBm IP3 (typ.), 7.0 dB conversion loss, and 32-pin QFN package. | Requires more PCB area and additional matching networks; optimized for high-volume consumer gateways. | Choose QM11036 when production cost and integration with Qorvo's PA modules are prioritized over minimal footprint. |
Compared with HMC218MS8, HMC1048LP3E trades compactness and lower loss for wider bandwidth, while QM11036 sacrifices some linearity and efficiency for higher integration density and ecosystem compatibility-making HMC218MS8 optimal for performance-critical, space-limited 5 GHz infrastructure.

FAQ
What is the recommended LO drive level for optimal performance of the HMC218MS8?
The HMC218MS8 achieves best conversion loss (6.5 dB typ.) and linearity (+18 dBm IP3) at +13 dBm LO drive. Performance remains usable down to +7 dBm LO, though conversion loss increases to 9.5 dB max and IP3 drops to +12 dBm min. Operating outside the +7 to +13 dBm range risks degraded isolation or compression.
Does the HMC218MS8 require external DC biasing or active components?
No, the HMC218MS8 is a fully passive double-balanced mixer built with GaAs Schottky diodes and on-die planar transformers. It requires no DC bias voltage or current, eliminating associated power supplies, decoupling networks, and thermal management overhead in RF designs.
Can the HMC218MS8 be used for both upconversion and downconversion?
Yes, the HMC218MS8 supports bidirectional operation: RF port serves as input for downconversion (RF→IF) and as output for upconversion (IF→RF), while LO and IF ports retain their defined roles. Its symmetric passive topology enables flexible use in TDD and FDD transceivers without hardware modification.
What is the maximum RF input power the HMC218MS8 can handle continuously?
The absolute maximum RF input power for the HMC218MS8 is +13 dBm. Exceeding this risks permanent damage to the GaAs diode junctions. For reliable operation, input power should remain ≤ +10 dBm under typical conditions, especially at elevated temperatures or with high peak-to-average ratios.
Is the HMC218MS8 pin-compatible with other Hittite mixers in the MSOP-8 package?
No, the HMC218MS8 has a unique pin assignment optimized for its double-balanced topology. While it shares the MSOP-8 outline with parts like HMC219MS8, pin functions (e.g., RF, LO, IF, ground) differ. Layout reuse requires verification against each device's specific schematic and footprint drawing.
