Product details
Overview
HMC277MS8E from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC passive single-balanced mixer in an MSOP-8 package, operating from 0.7–1.2 GHz RF/LO and DC–0.3 GHz IF. It delivers 9 dB typical conversion loss, +21 dBm input IP3, and 26 dB LO-to-RF isolation, enabling high-linearity upconversion/downconversion in cellular infrastructure transceivers.
For engineers reviewing the HMC277MS8E datasheet, HMC277MS8E pinout, HMC277MS8E application, or HMC277MS8E equivalent, key selection criteria include its RoHS-compliant matte Sn finish, MSL1 rating, -40°C to +85°C operating range, and pin-for-pin compatibility with HMC272MS8E for frequency band migration.
Technical Context
This passive mixer uses GaAs Schottky diodes and an on-chip planar transformer balun to achieve balanced RF port operation without external matching components. The LO port connects directly to the diodes, while the IF port is DC-coupled and rated for ≤40 mA DC current.
It operates as a downconverter with low-side LO by default, delivering SSB noise figure of 9–10.5 dB and LO-to-IF isolation of 8–12 dB. Absolute maximum ratings include +27 dBm LO drive and +13 dBm RF/IF input, with Class 1A ESD sensitivity requiring strict handling precautions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 0.7–1.2 GHz - supports GSM, CDMA, and WCDMA bands in basestation and repeater front-ends |
| IF Frequency Range | DC–0.3 GHz - enables baseband and low-IF architectures without external DC blocking at IF |
| Conversion Loss | 9 dB typical - defines signal attenuation between RF and IF ports; impacts receiver sensitivity and transmitter output power budget |
| Input IP3 | +21 dBm typical - determines third-order intermodulation distortion performance in multi-carrier cellular systems |
| LO-to-RF Isolation | 26 dB typical - reduces LO leakage into antenna paths, easing filter requirements in TDD/FDD systems |
| Operating Temperature | -40°C to +85°C - ensures stable mixer performance across outdoor basestation environmental conditions |
| ESD Sensitivity | HBM Class 1A - mandates grounded wrist straps and ionized air handling during PCB assembly |
Pinout & Package
Package: RoHS-compliant MSOP-8 with matte Sn lead finish, MSL1 rating, and max reflow temperature of 260°C. Exposed paddle must be soldered to RF ground per layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5 | GND | RF ground connection points - all must be soldered directly to PCB ground plane with multiple vias |
| 2 | LO | AC-coupled 50 Ω input - requires external DC blocking capacitor if LO source has DC offset |
| 4, 7 | N/C | No internal connection - may be grounded for mechanical stability without affecting RF performance |
| 6 | IF | DC-coupled output - supports DC-to-300 MHz IF; limits DC current to ≤40 mA to prevent device damage |
| 8 | RF | DC-coupled 50 Ω input/output - matched for direct integration into 50 Ω RF signal chains without external matching |
Key Features
| Feature | Design Value |
|---|---|
| Passive GaAs MMIC topology | Eliminates bias circuitry and supply regulation, reducing BOM count and board space in RF front-ends |
| Integrated planar transformer balun | Enables single-ended RF interface with inherent common-mode rejection, improving image suppression |
| No external matching required | Reduces design cycle time and layout sensitivity - RF/LO/IF ports are pre-matched to 50 Ω |
| Pin-for-pin compatible with HMC272MS8E | Allows reuse of existing PCB layouts when migrating from 1.7–3.0 GHz to 0.7–1.2 GHz band applications |
| RoHS-compliant matte Sn finish | Supports lead-free reflow processes up to 260°C peak temperature without solder joint reliability risk |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC272MS8E | Same MSOP-8 package and pinout; operates at 1.7–3.0 GHz RF/LO instead of 0.7–1.2 GHz | Targeted at PCS, UMTS, and LTE higher-band infrastructure rather than GSM/CDMA low-band | Select HMC272MS8E when redesigning for 1.9 GHz or 2.1 GHz bands while retaining identical PCB layout |
| ADL5801ACPZ-R7 | Active double-balanced mixer with 5 V supply; 700 MHz–1.2 GHz RF, 25 MHz–500 MHz IF; 8.5 dB conversion gain vs. 9 dB loss | Requires bias network and offers gain instead of loss; better for weak-signal receivers but adds power and noise | Choose ADL5801ACPZ-R7 only when system-level noise figure budget permits active gain and supply rails are available |
Compared with HMC277MS8E, HMC272MS8E provides identical form-factor and layout compatibility for higher-frequency upgrades, while ADL5801ACPZ-R7 trades passive simplicity for active gain and wider IF bandwidth-requiring careful evaluation of power, noise, and supply constraints.

FAQ
What is the recommended LO drive level for optimal performance of the HMC277MS8E?
The HMC277MS8E is characterized at +13 dBm LO drive, where it achieves 9 dB typical conversion loss, +21 dBm input IP3, and 26 dB LO-to-RF isolation. Operating below +11 dBm increases conversion loss and degrades IP3; exceeding +15 dBm risks compression and reduced linearity. Always verify LO drive with a calibrated RF source and power meter before full-system integration.
Can the HMC277MS8E be used for DC-coupled IF operation, and what are the current limits?
Yes, the HMC277MS8E IF port (Pin 6) is DC-coupled and supports operation from DC to 300 MHz. However, it must not sink or source more than 40 mA of DC current, as exceeding this limit may cause permanent device failure. For AC-coupled IF use, add a series capacitor sized to pass the desired IF bandwidth without insertion loss.
Is the HMC277MS8E pin-compatible with any other Hittite or Analog Devices mixers?
Yes, the HMC277MS8E is pin-for-pin compatible with the HMC272MS8E. Both share identical MSOP-8 footprint, pin numbering, and terminal functions. This allows direct PCB layout reuse when migrating between 0.7–1.2 GHz (HMC277MS8E) and 1.7–3.0 GHz (HMC272MS8E) frequency bands in infrastructure designs.
What is the maximum RF/IF input power rating for the HMC277MS8E?
The absolute maximum RF/IF input power rating for the HMC277MS8E is +13 dBm. Exceeding this level risks irreversible damage to the GaAs Schottky diodes. In practice, operation near compression (P1dB = +9 to +12 dBm) should be avoided in linear systems; maintain at least 6 dB back-off for multi-tone signals to preserve IP3 performance.
Does the HMC277MS8E require external matching components for 50 Ω operation?
No, the HMC277MS8E requires no external matching components. Its RF, LO, and IF ports are internally matched to 50 Ω, with the RF port balanced via an integrated planar transformer balun. This simplifies layout, improves repeatability, and eliminates tuning steps typically needed with discrete mixer solutions.
