Product details
Overview
HMC207AS8ETR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced mixer in an 8-lead SOIC package, operating from 0.7–2.0 GHz RF/LO and DC–0.3 GHz IF. It delivers 9 dB typical conversion loss, +17 dBm input IP3, and 45 dB LO/IF isolation at +13 dBm LO drive-enabling high-fidelity up/downconversion in base station transceivers.
For engineers reviewing the HMC207AS8ETR datasheet, HMC207AS8ETR pinout, HMC207AS8ETR application, or HMC207AS8ETR equivalent, key selection criteria include its passive architecture, DC-coupled 50 Ω ports, MSL1 reflow compatibility, and verified performance across –40°C to +85°C for wireless infrastructure signal chains.
Technical Context
This passive GaAs Schottky diode-based mixer uses on-chip planar transformer baluns to achieve inherent RF/LO/IF port balance and suppression. Its double-balanced topology rejects even-order harmonics and provides consistent LO leakage control without external filtering.
Operation requires +10 to +13 dBm LO drive for optimal linearity and noise figure; conversion loss remains stable across temperature (±0.5 dB from –40°C to +85°C), and all ports are DC-coupled with strict grounding requirements on pins 1,3,6,8 and the exposed package bottom.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 0.7–2.0 GHz: Supports full-band cellular and broadband wireless front-end operation without tuning. |
| IF Bandwidth | DC–0.3 GHz: Enables baseband and low-IF architectures including zero-IF receivers. |
| Conversion Loss | 9 dB typ. @ +13 dBm LO: Defines signal path gain budget; lower loss reduces cascaded noise figure impact. |
| Input IP3 | +17 dBm @ +13 dBm LO: Determines third-order intermodulation headroom in multi-carrier systems. |
| LO–IF Isolation | 45 dB min.: Reduces LO feedthrough into IF stage, easing filtering requirements in modulator/demodulator designs. |
| Operating Temperature | –40°C to +85°C: Validated for outdoor base station and industrial-grade RF module deployment. |
| ESD Rating | HBM Class 1A: Requires strict ESD handling during PCB assembly and test. |
Pinout & Package
Package: 8-lead SOIC (Small Outline IC), RoHS-compliant matte tin finish, MSL1 rating, max reflow 260°C. Exposed package bottom must be soldered to RF ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8 | GND | RF/DC ground terminals; all must be low-inductance soldered to PCB ground plane per RF layout best practices. |
| 2 | LO | DC-coupled 50 Ω LO input; requires clean, stable +10 to +13 dBm drive for optimal linearity. |
| 4 | N/C | No internal connection; may be grounded without performance impact but not required. |
| 5 | IF | DC-coupled IF output; supports DC–300 MHz; current limited to ±10 mA to prevent damage. |
| 8 | RF | DC-coupled 50 Ω RF input; matched for direct integration into 50 Ω signal paths. |
Key Features
| Feature | Design Value |
|---|---|
| Passive GaAs MMIC Architecture | Eliminates bias circuitry, enabling ultra-low power system-level design and eliminating quiescent current dependencies. |
| On-Chip Planar Transformer Baluns | Ensures intrinsic amplitude/phase balance across RF/LO/IF ports without external hybrid couplers or ferrite transformers. |
| DC-Coupled Ports | Supports true zero-IF and complex I/Q architectures without blocking capacitors at RF/LO/IF interfaces. |
| High LO Suppression | 45–50 dB LO-to-IF/RF isolation enables carrier-suppressed modulation and simplifies post-mixer filtering. |
| MSL1 Reflow Compatibility | Enables standard lead-free SMT assembly with peak temperature up to 260°C without reliability degradation. |
Applications
| Cellular Base Station Transceivers | Cable Modem Upstream Path |
|---|---|

IC Role / Device Role / Timing Role: Biphase modulator functioning as analog phase comparator with linear output vs. phase difference. Use Value: Balanced topology rejects common-mode noise, and DC-coupled IF output enables direct op-amp integration for loop filter implementation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC207AS8 | Sn/Pb lead finish, 235°C max reflow, non-RoHS compliant. | Legacy production use where Pb-containing solder is permitted and MSL1 handling is unchanged. | Select HMC207AS8 only if RoHS exemption applies and existing reflow profile uses 235°C peak. |
| QH1007 | Wider IF bandwidth (DC–1.0 GHz), higher conversion loss (10.5 dB), same 0.7–2.0 GHz RF/LO range. | Better suited for wideband IF digitization; less ideal for narrowband IF filtering due to higher loss. | Choose QH1007 when IF bandwidth >300 MHz is required and 1.5 dB higher conversion loss is acceptable. |
Compared with HMC207AS8ETR, HMC207AS8 offers identical RF/IF performance but lacks RoHS compliance, while QH1007 trades 1.5 dB higher conversion loss for doubled IF bandwidth-making HMC207AS8ETR optimal for cost-sensitive, RoHS-mandated, narrowband IF systems.

FAQ
What is the recommended LO drive level for optimal performance of the HMC207AS8ETR?
The HMC207AS8ETR achieves best conversion loss, IP3, and noise figure at +13 dBm LO drive. Performance degrades below +10 dBm (increased conversion loss, reduced IP3) and above +15 dBm (risk of compression and potential damage). The datasheet specifies +10 to +13 dBm as the nominal operating range, and HMC207AS8ETR must never be driven beyond +27 dBm absolute maximum.
Can the HMC207AS8ETR be used for zero-IF (direct-conversion) receiver designs?
Yes-the HMC207AS8ETR supports zero-IF operation because all ports (RF, LO, IF) are DC-coupled and rated for DC–300 MHz IF bandwidth. Its double-balanced topology inherently suppresses LO feedthrough and even-order distortion, making HMC207AS8ETR suitable for I/Q demodulator implementations when paired with appropriate quadrature LO generation.
Is the HMC207AS8ETR pin-compatible with the non-RoHS HMC207AS8 variant?
Yes-HMC207AS8ETR and HMC207AS8 share identical pinout, package dimensions, and electrical specifications. The only differences are lead finish (matte Sn vs. Sn/Pb), MSL1 reflow profile (260°C vs. 235°C), and RoHS compliance. No PCB layout change is needed when substituting HMC207AS8ETR for HMC207AS8 in new designs.
What grounding requirements apply to the HMC207AS8ETR package bottom and leads?
The exposed package bottom and pins 1, 3, 6, and 8 must be soldered to a low-inductance RF ground plane using multiple thermal vias. Per the datasheet, failure to ground the bottom pad causes degraded isolation and increased conversion loss. HMC207AS8ETR performance validation assumes full mechanical and electrical contact between the package underside and PCB ground.
Does the HMC207AS8ETR require external DC blocking capacitors on any port?
No-HMC207AS8ETR has fully DC-coupled RF, LO, and IF ports. External DC blocking is optional only on the IF port if DC operation is not required; otherwise, no capacitors are needed. Applying DC blocking on RF or LO ports would disrupt impedance matching and degrade HMC207AS8ETR conversion loss and isolation performance.
