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/IF ports, -40°C to +85°C operating range, MSL1 reflow compatibility, and verified performance as a biphase modulator or phase comparator in portable wireless infrastructure.
Technical Context
The HMC207AS8 is a passive GaAs Schottky diode-based MMIC mixer with integrated planar transformer baluns, enabling true double-balanced operation without external hybrids. Its architecture provides inherent suppression of even-order harmonics and LO feedthrough, critical for carrier-suppressed modulation schemes.
It operates with DC-coupled RF, LO, and IF ports-requiring no external bias tees-and supports both upconversion and downconversion across its full 0.7–2.0 GHz RF/LO bandwidth while maintaining consistent conversion loss and isolation over temperature (-40°C to +85°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 0.7–2.0 GHz: Full-band operation without tuning or external matching networks |
| IF Frequency Range | DC–0.3 GHz: Supports baseband and low-IF architectures including zero-IF receivers |
| Conversion Loss | 9 dB typ. @ +13 dBm LO: Predictable signal path gain budgeting in cascaded RF chains |
| Input IP3 | +17 dBm @ +13 dBm LO: Enables robust linearity in multi-carrier cable modem and LTE base station front-ends |
| LO/IF Isolation | 45 dB min. @ +13 dBm LO: Reduces LO leakage into sensitive IF stages, easing filtering requirements |
| Operating Temperature | -40°C to +85°C: Validated performance across industrial and outdoor wireless equipment environments |
| ESD Rating | HBM Class 1A: Requires strict ESD handling per JEDEC JESD22-A114 but supports standard SMT assembly |
Pinout & Package
Package: 8-lead plastic SOIC (Small Outline IC), MSL1, low-stress molded body, Sn/Pb lead finish, 235°C max reflow peak. Ground leads (1,3,6,8) must be soldered to PCB RF ground plane; package bottom also requires grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8 | GND | RF/DC ground connections; all four must be soldered to minimize parasitic inductance and ensure isolation integrity |
| 2 | LO | DC-coupled 50 Ω matched port; accepts +13 dBm nominal drive without external biasing or matching |
| 4 | N/C | No internal connection; may be grounded externally without degrading RF performance |
| 5 | IF | DC-coupled port; supports DC–300 MHz; limited to ±10 mA current to prevent damage |
| 8 | RF | DC-coupled 50 Ω matched port; handles RF input up to +13 dBm without saturation |
Key Features

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 version with 100% matte Sn finish and 260°C reflow rating; identical electrical specs | Required for lead-free manufacturing; same RF performance and pinout as HMC207AS8 | Select HMC207AS8E for RoHS-compliant production; HMC207AS8 remains valid for Sn/Pb assembly |
| ADL5801ACPZ-R7 | Active 0.4–2.7 GHz mixer with 22 dBm IIP3 but requires 5 V supply and bias control; 12 dB conversion loss | Better linearity at cost of power consumption and complexity; not drop-in compatible | Choose ADL5801ACPZ-R7 only when higher IIP3 justifies added supply and layout overhead |
Compared with HMC207AS8E, the HMC207AS8 offers identical RF performance with Sn/Pb solder compatibility, while ADL5801ACPZ-R7 trades passive simplicity for active linearity-making HMC207AS8 optimal for low-power, supply-constrained, or legacy-assembly 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 conversion loss and linearity occur at +13 dBm LO drive, where typical conversion loss is 9 dB and input IP3 reaches +17 dBm. Exceeding +13 dBm improves conversion loss marginally but increases risk of compression and spurious generation.
Can the HMC207AS8 operate with DC-coupled IF signals?
Yes, the HMC207AS8 IF port is DC-coupled and supports operation from DC to 300 MHz. However, the IF pin must not source or sink more than ±10 mA DC current, or permanent device failure may occur. For AC-coupled IF paths, a series capacitor sized for the lowest IF frequency is recommended.
Is the HMC207AS8 pin-compatible with the HMC207AS8E?
Yes, the HMC207AS8 and HMC207AS8E share identical pinout, package dimensions, and electrical specifications. The only differences are lead finish (Sn/Pb vs. 100% matte Sn) and MSL reflow profile (235°C vs. 260°C peak), making them mechanically and electrically interchangeable in most layouts.
What is the recommended PCB grounding strategy for the HMC207AS8?
All ground pins (1, 3, 6, 8) and the exposed package bottom must be soldered directly to a solid RF ground plane using multiple vias. Signal traces should maintain 50 Ω impedance, and ground return paths must be minimized-especially for LO and RF lines-to preserve the specified 40–45 dB isolation performance.
Does the HMC207AS8 require external baluns or matching components?
No, the HMC207AS8 integrates planar transformer baluns on-die and presents 50 Ω matched, DC-coupled ports for RF, LO, and IF. No external baluns, bias tees, or matching networks are required for standard operation within its 0.7–2.0 GHz RF/LO and DC–0.3 GHz IF ranges.
