Product details
Overview
HMC207AS8 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 HMC207AS8 datasheet, HMC207AS8 pinout, HMC207AS8 application, or HMC207AS8 equivalent, key selection criteria include its DC-coupled 50 Ω RF/LO ports, thermal stability across –40°C to +85°C, MSL1 reflow compatibility, and verified performance in cable modem front-ends and portable wireless IF stages.
Technical Context
The HMC207AS8 implements a passive GaAs Schottky diode core with on-chip planar transformer baluns for true double-balanced operation. Its RF/LO/IF ports are all DC-coupled and impedance-matched to 50 Ω, enabling direct integration without external DC blocking or matching networks in most SMT layouts.
Performance is specified at +13 dBm LO drive and 70 MHz IF, with consistent conversion loss (9–10.5 dB), noise figure (9–10.5 dB), and isolation (LO/RF ≥40 dB, LO/IF ≥45 dB) across temperature and frequency-supporting stable modulation/demodulation in regulated wireless infrastructure.
Key Specifications

|---|---|
| Frequency Range (RF/LO) | 0.7–2.0 GHz - supports full-band operation in UHF/L-band base stations and cable modems |
| IF Bandwidth | DC–0.3 GHz - enables baseband-to-300 MHz IF processing without external DC blocking |
| Conversion Loss | 9 dB typ. @ +13 dBm LO - defines minimum signal path gain penalty in receiver chain design |
| Input IP3 | +17 dBm typ. @ +13 dBm LO - determines third-order intermodulation headroom in multi-carrier systems |
| LO/IF Isolation | 45 dB min. - suppresses LO leakage into IF output, critical for low-noise demodulator stages |
| P1dB (Input) | +11 dBm typ. @ +13 dBm LO - sets maximum linear input power before 1 dB compression |
| Operating Temp. | –40°C to +85°C - validated for industrial and outdoor telecom equipment environments |
Pinout & Package
Package: 8-lead SOIC (Small Outline IC), RoHS-compliant variant not applicable to HMC207AS8; lead finish is Sn/Pb solder, MSL1 rated, max reflow peak 235°C. Package bottom must be soldered to PCB RF ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8 | GND | RF/DC ground terminals - all four must be soldered to PCB ground plane for optimal isolation and thermal dissipation |
| 2 | LO | DC-coupled 50 Ω LO input - accepts +13 dBm drive directly; no external bias tee required |
| 4 | N/C | No internal connection - may be grounded without performance impact |
| 5 | IF | DC-coupled IF output - supports DC-to-300 MHz operation; current limited to ±10 mA |
| 8 | RF | DC-coupled 50 Ω RF port - bidirectional use as RF input (downconverter) or output (upconverter) |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC207AS8E | RoHS-compliant variant with matte Sn lead finish and 260°C reflow rating; identical electrical specs | Required for lead-free manufacturing; same RF/IF/LO performance and pinout | Select HMC207AS8E when RoHS compliance and Pb-free assembly are mandatory |
| ADL5801ACPZ-R7 | SiGe active mixer with 2.5 V supply, 700–2700 MHz RF, 10 dB lower IP3 (+7 dBm), requires external bias | Better noise figure (8.5 dB) but higher LO drive sensitivity; needs DC bias network | Choose ADL5801ACPZ-R7 only if system-level power budget allows active bias and noise dominates over linearity |
Compared with HMC207AS8E, the HMC207AS8 offers identical RF performance with Sn/Pb solder compatibility, while ADL5801ACPZ-R7 trades passive simplicity and high IP3 for lower noise and active bias dependency-making HMC207AS8 optimal for cost-sensitive, high-linearity, leaded-SMT telecom designs.

FAQ
What is the maximum LO drive level for the HMC207AS8?
The HMC207AS8 supports a maximum LO drive of +27 dBm per absolute maximum ratings. However, optimal performance-including 9 dB conversion loss and +17 dBm IP3-is achieved at +13 dBm LO drive. Exceeding +13 dBm improves conversion loss marginally but increases risk of diode compression and reduced linearity. Always verify thermal derating above +85°C ambient.
Can the HMC207AS8 be used as a phase comparator?
Yes, the HMC207AS8 can function as a biphase modulator (phase comparator) due to its double-balanced topology and symmetric RF/LO/IF response. When driven with two coherent signals at RF and LO ports, the IF output amplitude is proportional to the cosine of their phase difference. This mode is documented in Hittite's application notes for PLL phase alignment and carrier recovery circuits using HMC207AS8.
Is DC blocking required on the IF port of the HMC207AS8?
No, DC blocking is not required on the IF port of the HMC207AS8 because it is DC-coupled and supports operation from DC to 300 MHz. However, if the downstream circuit cannot tolerate DC offset or exceeds ±10 mA current sourcing/sinking capability, an external series capacitor must be added. For true DC-coupled IF paths-such as direct connection to baseband ADCs-the HMC207AS8 operates without modification.
What is the recommended PCB grounding strategy for the HMC207AS8?
The HMC207AS8 requires all GND pins (1, 3, 6, 8) plus the exposed package bottom to be soldered directly to a solid RF ground plane. Use ≥6 via holes per ground pin connecting top-layer ground to internal/bottom ground planes. Maintain 50 Ω controlled impedance on RF/LO/IF traces, and avoid stubs or discontinuities near the device. Evaluation board 101783 (Rogers 4350) demonstrates this layout per Hittite's reference design.
Does the HMC207AS8 require external biasing or matching components?
No, the HMC207AS8 is a passive GaAs MMIC mixer requiring no external bias voltage or current. All ports (RF, LO, IF) are DC-coupled and internally matched to 50 Ω, eliminating the need for external baluns, bias tees, or matching networks in standard 50 Ω systems. Only external DC blocking may be needed on IF if downstream circuitry is AC-coupled or current-limited.
