Product details
Overview
HMC218BMS8GETR from Analog Devices is a GaAs MMIC double-balanced passive mixer in an 8-lead MSOP package, operating from 3.5–8 GHz RF/LO and DC–1.6 GHz IF. It delivers 7 dB typical conversion loss, +17 dBm input IP3, and 38 dB LO-to-RF isolation, enabling high-linearity down-conversion in WiMAX base stations and portable wireless transceivers.
For engineers reviewing the HMC218BMS8GETR datasheet, HMC218BMS8GETR pinout, HMC218BMS8GETR application, or HMC218BMS8GETR equivalent, key selection criteria include its ultra-miniature MSOP-8 footprint, DC-coupled RF/LO/IF ports, wide IF bandwidth supporting DC–1.6 GHz, and verified performance across temperature (−40°C to +85°C) and LO drive (+9 to +15 dBm).
Technical Context
This passive double-balanced mixer uses GaAs Schottky diodes and on-chip planar transformer baluns to achieve inherent LO-RF and LO-IF isolation without external filtering. Its topology supports both high-side LO down-conversion (e.g., 5.25 GHz LO → 5.15 GHz RF → 100 MHz IF) and low-side LO up-conversion (e.g., 100 MHz IF → 4.6 GHz RF with 4.5 GHz LO).
Performance is specified at TA = +25°C, IF = 100 MHz, LO = +13 dBm, and LSB operation, with validated metrics including 45 dB input IP2, 11 dBm input P1dB, and 120 °C/W thermal resistance from junction to ground paddle - critical for thermal management in compact RF front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 3.5–8 GHz: Supports full-band operation in WiMAX (3.5 GHz), LTE-U (5 GHz), and 5G FR1 (6–8 GHz) infrastructure. |
| IF Bandwidth | DC–1.6 GHz: Enables baseband I/Q demodulation and wideband IF sampling without AC coupling constraints. |
| Conversion Loss | 7 dB typical: Low signal attenuation preserves SNR in receiver chains; measured at LO = +13 dBm, RFIN = −10 dBm, IF = 100 MHz. |
| Input IP3 | +17 dBm typical: High linearity reduces intermodulation distortion in dense-spectrum environments like repeaters and access points. |
| LO–RF Isolation | 38 dB typical: Minimizes LO leakage into antenna paths, easing filter requirements in TDD/FDD transceivers. |
| Operating Temperature | −40°C to +85°C: Qualified for outdoor base station enclosures and industrial-grade portable radios. |
| Thermal Resistance | 120 °C/W (junction-to-paddle): Requires direct thermal connection of exposed paddle to PCB ground plane for sustained +13 dBm LO drive. |
Pinout & Package
Package: 8-lead MSOP (Mini Small Outline Package) with exposed ground paddle; RoHS-compliant, matte Sn lead finish, MSL1 rating (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | LO | DC-coupled 50 Ω matched port; accepts +9 to +15 dBm LO drive; must be impedance-controlled on PCB. |
| 2, 3, 6, 7 | GND | RF/DC ground terminals; require low-inductance connection to top-layer ground plane and multiple vias to internal ground layers. |
| 4 | N/C | No internal connection; data measured with pin grounded externally - recommended for mechanical stability and EMI suppression. |
| 5 | IF | DC-coupled output; supports DC–1.6 GHz; limits current to ≤2 mA when used for true DC-coupled applications. |
| 8 | RF | DC-coupled 50 Ω matched RF input; optimized for −10 dBm signal level in standard test conditions. |
Key Features
| Feature | Design Value |
|---|---|
| Passive Double-Balanced Topology | Eliminates need for external baluns or bias networks; provides inherent common-mode rejection and harmonic suppression. |
| GaAs MMIC Construction | Enables consistent performance across frequency bands without discrete component variation; supports high-volume SMT assembly. |
| Ultra-Miniature MSOP-8 Footprint | Reduces PCB area by >50% vs. traditional SOIC-8 mixers; compatible with automated optical alignment during placement. |
| DC-Coupled Ports | Removes external DC-blocking capacitors from RF/LO/IF paths, lowering BOM count and preserving low-frequency response. |
| High Input IP2 (45 dBm) | Suppresses second-order intermodulation products in asymmetric signal environments (e.g., adjacent-channel interference in PLMR). |
Applications
| WiMAX Base Stations | Public Safety Radios |
|---|---|
Use Scenario: Down-converting 3.5 GHz WiMAX signals to 100 MHz IF in outdoor sectorized base stations with high adjacent-channel interference.

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP3E | Wider RF/LO range (2–12 GHz), higher conversion loss (8.5 dB typ), larger 16-lead LCC package. | Better suited for Ka-band test equipment; less optimal for compact 5 GHz WiMAX modules due to size and loss. | Select HMC1048LP3E only when extending beyond 8 GHz or requiring hermetic packaging. |
| ADL5801ACPZ-R7 | Active mixer with integrated LO amplifier; 5.8–10.5 GHz RF, +22 dBm IP3, requires +5 V bias and consumes 120 mA. | Higher integration but adds power, heat, and noise; unsuitable for ultra-low-power portable receivers. | Choose ADL5801ACPZ-R7 only when LO drive is insufficient or active gain is required before IF ADC. |
Compared with HMC1048LP3E and ADL5801ACPZ-R7, the HMC218BMS8GETR offers the best trade-off of miniature size, passive operation, and verified 3.5–8 GHz performance - making it optimal for cost-sensitive, thermally constrained wireless infrastructure modules where external LO amplification and biasing are undesirable.

FAQ
What is the maximum LO power rating for the HMC218BMS8GETR?
The absolute maximum LO power rating for the HMC218BMS8GETR is +27 dBm. However, typical operation uses +13 dBm LO drive to achieve optimal conversion loss (7 dB) and IP3 (+17 dBm). Exceeding +15 dBm may increase distortion without meaningful gain improvement and risks accelerated aging under continuous operation.
Can the HMC218BMS8GETR operate with DC-coupled IF output in baseband applications?
Yes, the HMC218BMS8GETR supports true DC-coupled IF operation via Pin 5. When used this way, the IF port must not source or sink more than ±2 mA DC current to avoid non-function or permanent damage. For AC-coupled IF paths above 100 kHz, a series capacitor is recommended to block DC offset while passing the full 1.6 GHz bandwidth.
Is the HMC218BMS8GETR pin-compatible with other Hittite MSOP-8 mixers like the HMC219MS8GETR?
No, the HMC218BMS8GETR is not pin-compatible with the HMC219MS8GETR. While both use MSOP-8 packages, the HMC219MS8GETR has different pin assignments (e.g., RF and LO swapped) and operates over 4–8 GHz with distinct balun topology. PCB layout must be redesigned for each part; no drop-in replacement is supported.
Does the HMC218BMS8GETR require external baluns or matching networks?
No, the HMC218BMS8GETR integrates on-chip planar transformer baluns for all ports (RF, LO, IF), eliminating the need for external baluns or impedance-matching components. All ports are DC-coupled and internally matched to 50 Ω, allowing direct connection to 50 Ω transmission lines with only proper grounding of pins 2, 3, 6, 7 and the exposed paddle.
What evaluation board is recommended for prototyping with the HMC218BMS8GETR?
The EV1HMC218BMS8G evaluation board (P/N 101828) is the official Analog Devices reference design for the HMC218BMS8GETR. It features Rogers 4350 substrate, SMA connectors (J1, J3), and optimized 50 Ω routing with multiple ground vias - enabling accurate characterization of conversion loss, isolation, and linearity before custom PCB spin.
