Product details
Overview
HMC214MS8ETR from Analog Devices (formerly Hittite Microwave) is a passive GaAs MMIC single-ended mixer for RF-to-IF downconversion and upconversion in 2.4–4.0 GHz systems, delivering +34 dBm input IP3, +22 dBm P1dB, and 10 dB typical conversion loss at +17 dBm LO drive - deployed in WiMAX base stations and fixed wireless access transceivers.
For engineers reviewing the HMC214MS8ETR datasheet, HMC214MS8ETR pinout, HMC214MS8ETR application, or HMC214MS8ETR equivalent, key selection criteria include its DC–1 GHz IF bandwidth, 25–30 dB LO-to-RF isolation, MSOP-8 package footprint (14.8 mm²), and zero-bias operation requiring no external components.
Technical Context
The HMC214MS8ETR is a passive FET-based double-balanced mixer topology optimized for high linearity over 2.4–4.0 GHz RF/LO bands and DC–1 GHz IF output. Its monolithic GaAs construction enables stable performance across –40°C to +85°C without bias circuitry or matching networks.
It operates with low-side LO injection and supports both downconversion (e.g., 3.5 GHz RF → 200 MHz IF) and upconversion modes. LO drive range is tightly specified at +15 to +19 dBm, with optimal performance at +17 dBm, where conversion loss remains flat and IP3 peaks at +34 dBm.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 2.4–4.0 GHz - covers full WiMAX 3.5 GHz band and adjacent licensed/unlicensed spectrum. |
| Input IP3 (Typ.) | +34 dBm - enables robust handling of strong interferers in dense RF environments like FWA base stations. |
| Conversion Loss (Typ.) | 10 dB - defines signal path attenuation; requires minimal gain compensation in IF chain design. |
| LO to RF Isolation | 28 dB (typ.) - suppresses LO leakage into antenna path, easing filtering requirements in transmit modules. |
| IF Bandwidth | DC–1 GHz - supports wideband modulation schemes including OFDMA and burst-mode signaling. |
| P1dB (Input) | +22 dBm - allows direct connection to power amplifiers or LNA outputs without attenuators. |
| LO Drive Level | +17 dBm (typ.) - matches standard PLL/VCO output levels; eliminates need for LO buffer stages. |
Pinout & Package
Package: 8-lead MSOP (Mini Small Outline Package), RoHS-compliant, 14.8 mm² footprint, thermal resistance 270 °C/W (junction-to-lead), MSL1 rating with 260 °C peak reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | LO | DC-coupled 50 Ω input; requires external blocking capacitor if LO source has DC offset. |
| 2, 4 | N/C | No internal connection; must be grounded externally per evaluation board layout for RF stability. |
| 3, 6, 7 | GND | RF ground terminals; all must be soldered directly to PCB ground plane with multiple vias. |
| 5 | IF | DC-coupled output; supports DC–1 GHz; current limited to ±40 mA to prevent damage. |
| 8 | RF | DC-coupled 50 Ω RF input; matched for broadband operation without external matching. |
Key Features
| Feature | Design Value |
|---|---|
| No external components required | Eliminates discrete baluns, bias tees, and matching networks - reduces BOM count and layout area by >30%. |
| Ultra-small MSOP-8 package | 14.8 mm² footprint enables compact RF front-end integration in space-constrained modules. |
| High dynamic range (+34 dBm IP3) | Outperforms many active mixers while avoiding DC power, heat, and noise penalties. |
| DC–1 GHz IF bandwidth | Supports zero-IF, low-IF, and wideband IF architectures without redesigning IF filtering. |
| Zero-bias operation | Removes need for bias supply, regulators, and decoupling - simplifies power domain partitioning. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP4E | Wider RF range (1.7–4.2 GHz); higher LO drive (+20 dBm); larger 4×4 mm QFN package. | Better suited for multi-band cellular infrastructure; less compact than HMC214MS8ETR. | Select when broader frequency coverage or higher LO tolerance is required over size constraints. |
| ADL5801ACPZ-R7 | Active double-balanced mixer; +26 dBm IP3; requires +5 V bias; 24-lead LFCSP package. | Higher noise figure (9.5 dB vs. 10–11.5 dB); needs bias network but offers better LO suppression (45 dB). | Choose when lower noise or superior LO rejection outweighs power consumption and board area trade-offs. |
Compared with HMC1048LP4E and ADL5801ACPZ-R7, the HMC214MS8ETR delivers best-in-class IP3 per unit area and zero-bias simplicity - ideal for cost-sensitive, size-constrained FWA and WiMAX modules where LO drive is well-controlled.

FAQ
What is the recommended LO drive level for optimal performance of the HMC214MS8ETR?
The HMC214MS8ETR achieves best-in-class IP3 (+34 dBm) and lowest conversion loss (10 dB) at +17 dBm LO drive. Operation between +15 and +19 dBm is supported, but deviation outside this range degrades linearity and increases conversion loss. The HMC214MS8ETR does not require LO buffering if the source meets this drive specification.
Does the HMC214MS8ETR require external bias or DC blocking components?
No. The HMC214MS8ETR is a passive GaAs FET mixer with zero-bias operation - no external power supply or bias network is needed. DC blocking capacitors are only required on LO and RF ports if those sources have non-zero DC potential; the IF port is DC-coupled and rated for ±40 mA.
Can the HMC214MS8ETR be used for upconversion, and what is its upconversion IP3?
Yes, the HMC214MS8ETR supports upconversion with verified +31 dBm input IP3 at +17 dBm LO drive and 200 MHz IF. Performance remains consistent across its 2.4–4.0 GHz RF/LO range, making it suitable for FWA transmitters and test equipment requiring clean RF synthesis.
What is the thermal resistance and maximum channel temperature of the HMC214MS8ETR?
The HMC214MS8ETR has a junction-to-lead thermal resistance of 270 °C/W and a maximum channel temperature of 150 °C. At 85 °C ambient, its continuous power dissipation is 240 mW, derating linearly above that temperature. Proper PCB grounding via pins 3/6/7 and thermal vias is essential to maintain reliability.
Is the HMC214MS8ETR pin-compatible with the non-RoHS HMC214MS8 variant?
Yes - the HMC214MS8ETR and HMC214MS8 share identical pinout, package dimensions, and electrical specifications. The only differences are lead finish (100% matte Sn vs. Sn/Pb) and MSL1 reflow profile (260 °C vs. 235 °C), making them drop-in replacements in new designs adhering to RoHS requirements.
