Product details
Overview
102781-HMC272AMS8 from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC single-balanced passive mixer in an MSOP-8 package, operating across 1.7–3.0 GHz RF/LO and DC–0.8 GHz IF bands, delivering 10.5 dB typical conversion loss at +10 dBm LO drive and 100 MHz IF, with +20 dBm input IP3 and 32 dB LO-to-RF isolation - ideal for PCS up/down conversion and W-CDMA front-end signal processing.
For engineers reviewing the 102781-HMC272AMS8 datasheet, 102781-HMC272AMS8 pinout, 102781-HMC272AMS8 application, or 102781-HMC272AMS8 equivalent, key selection criteria include its ultra-miniature MSOP-8 footprint, balanced RF port architecture, LO-driven diode topology, and verified performance across temperature (−40°C to +85°C) and LO drive levels (+7 to +13 dBm).
Technical Context
This passive MMIC mixer uses integrated GaAs Schottky diodes and a planar transformer balun to achieve RF port balancing while connecting the LO directly to the diode junctions - enabling high linearity without external biasing. Its architecture delivers consistent conversion loss and isolation across the 1.7–3.0 GHz band with minimal temperature drift.
The device operates without DC power, relying solely on LO injection; its RF and IF ports are unbalanced, while the RF path is balanced via on-chip balun. Spurious output suppression exceeds 37 dBc for 2LO–RF mixing products at 2.6 GHz RF input and 2.2 GHz LO, supporting clean spectral translation in dense RF environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 1.7–3.0 GHz - supports full PCS (1.85–1.99 GHz), W-CDMA (2.11–2.17 GHz), and 2.4 GHz ISM bands without retuning. |
| IF Bandwidth | DC–0.8 GHz - enables baseband I/Q downconversion and wideband IF sampling up to 800 MHz. |
| Conversion Loss | 10.5 dB typ @ +10 dBm LO, 100 MHz IF - defines minimum gain budget required in receiver chain before IF amplification. |
| Input IP3 | +20 dBm typ @ +10 dBm LO - determines third-order intermodulation headroom in multi-carrier cellular receivers. |
| LO-to-RF Isolation | 32 dB max @ 400 MHz IF - reduces LO leakage into antenna path, easing filter requirements in transceiver designs. |
| Operating Temp | −40°C to +85°C - validated for industrial and outdoor wireless infrastructure deployment. |
| ESD Rating | HBM Class 1A - requires strict handling per ESD-sensitive device protocols during PCB assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP3E | Wider RF range (1.5–4.0 GHz), higher conversion loss (12.5 dB typ), same MSOP-8 package. | Better suited for 3.5 GHz WiMAX or LTE-A bands where extended upper frequency coverage is required. | Select when RF band extends beyond 3.0 GHz; verify LO drive compatibility (+13 dBm max). |
| Qorvo QM11024 | 0.7–3.8 GHz RF range, 9.5 dB conversion loss, 30 dB LO-RF isolation, 2.0 × 2.0 mm DFN package. | Smaller footprint and lower loss benefit space-constrained IoT gateways but lacks MSOP-8 mechanical compatibility. | Choose for miniaturized designs where board re-layout is acceptable and tighter IF bandwidth (DC–600 MHz) suffices. |
Compared with HMC1048LP3E and QM11024, the 102781-HMC272AMS8 offers optimal balance of size, linearity (+20 dBm IP3), and isolation (32 dB) specifically within the 1.7–3.0 GHz window - making it preferred for PCS and W-CDMA systems where legacy MSOP-8 layout reuse and proven thermal performance are critical.

FAQ
What is the recommended LO drive level for optimal performance of the 102781-HMC272AMS8?
The 102781-HMC272AMS8 achieves best linearity and conversion loss at +10 dBm LO drive. Performance remains stable between +7 dBm and +13 dBm; below +7 dBm, conversion loss increases and IP3 degrades. The 102781-HMC272AMS8 does not require DC bias, simplifying LO driver stage design.
Does the 102781-HMC272AMS8 require external baluns or matching networks?
No - the 10272AMS8 integrates a planar transformer balun for the RF port, eliminating need for external baluns. The LO and IF ports are single-ended and designed for 50 Ω impedance; only standard RF layout practices (controlled impedance traces, ground vias) are required. The 102781-HMC272AMS8 evaluation board (102643) confirms this simplified interface.
Is the 102781-HMC272AMS8 RoHS-compliant?
The 102781-HMC272AMS8 uses Sn/Pb lead finish and is not RoHS-compliant; however, the pin-compatible HMC272AMS8E variant features 100% matte Sn plating and meets RoHS Directive 2011/65/EU. Both share identical electrical specs and MSOP-8 packaging, differing only in finish and MSL reflow profile (235°C vs. 260°C).
What is the maximum RF input power the 102781-HMC272AMS8 can handle?
The absolute maximum RF/IF input rating for the 102781-HMC272AMS8 is +13 dBm. Continuous operation above this level risks permanent damage to the GaAs Schottky diodes. For reliable 1 dB compression point, the 102781-HMC272AMS8 delivers +11 dBm input P1dB at +10 dBm LO drive and 100 MHz IF.
How does temperature affect conversion loss in the 102781-HMC272AMS8?
Conversion loss variation over temperature is minimal: ±0.5 dB from −40°C to +85°C at +10 dBm LO and 100 MHz IF. The 102781-HMC272AMS8 datasheet plots confirm stable gain slope across frequency and temperature, supporting uncalibrated operation in industrial environments without compensation circuitry.
