Product details
Overview
HMC171C8TR from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced mixer in a non-hermetic ceramic SMT package, operating from 7–10 GHz RF/LO and DC–2 GHz IF. It delivers 9 dB typical conversion loss, 32 dB LO-to-RF isolation, and +16 dBm input IP3, enabling high-dynamic-range up/downconversion in microwave radios without DC bias.
For engineers reviewing the HMC171C8TR datasheet, HMC171C8TR pinout, HMC171C8TR application, or HMC171C8TR equivalent, this passive diode/balun mixer supports critical RF front-end design where size, surface-mount compatibility, and LO/RF isolation are essential - especially in 5.8 GHz ISM and point-to-point radio systems.
Technical Context
The HMC171C8TR implements a passive GaAs MMIC architecture with integrated baluns, delivering inherent symmetry for high port-to-port isolation. Its RF/LO frequency range (7–10 GHz) and IF bandwidth (DC–2 GHz) support both upconversion and downconversion with no external biasing required.
Key performance stems from high linearity: +16 dBm input IP3 and +10 dBm 1 dB compression enable robust handling of large-signal interferers. Noise figure (9 dB typ.) equals conversion loss, confirming its passive nature and predictable system noise contribution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 7.0–10.0 GHz - Supports full-band operation in X-band microwave radios and 5.8 GHz ISM transceivers. |
| IF Frequency Range | DC–2.0 GHz - Enables baseband and low-IF architectures including zero-IF receivers and I/Q modulators. |
| Conversion Loss | 9 dB typ. - Directly defines signal attenuation in cascade gain budget; matches SSB noise figure. |
| LO to RF Isolation | 32 dB typ. - Reduces LO leakage into antenna path, easing filtering requirements in transmit chains. |
| Input IP3 | +16 dBm typ. - Determines third-order intermodulation suppression capability in dense RF environments. |
| 1 dB Compression (Input) | +10 dBm typ. - Defines maximum usable input power before gain deviation exceeds 1 dB. |
| LO Drive Level | +10 dBm - Fixed optimal drive level; lower drive increases conversion loss, higher drive risks damage. |
Pinout & Package
The HMC171C8TR is housed in an 8-lead ceramic SMT package (HMC171C8 footprint), with leads designated for RF, LO, IF, and ground connections. The exposed paddle must be soldered to PCB RF ground per layout guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Ground (RF/LO/IF common) | All four corner pins and exposed paddle form unified RF ground reference; mandatory for balun balance and isolation. |
| 5 | RF Input | Differential RF port (balanced); requires 50 Ω microstrip matching network on PCB. |
| 6 | LO Input | Differential LO port (balanced); accepts +10 dBm drive; sensitive to impedance mismatch. |
| 7 | IF Output | Differential IF output; DC-coupled; compatible with baseband amplifiers or ADC drivers. |
| 8 | NC / Ground Tie | No internal connection; recommended to tie to ground plane for mechanical stability and EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| No DC bias required | Enables simplified power architecture - eliminates bias tees, regulators, and associated noise sources in RF paths. |
| High LO-to-RF isolation (32 dB) | Reduces need for external LO filtering in transmitters, lowering BOM count and board area in compact radios. |
| DC–2 GHz IF bandwidth | Supports direct-conversion receivers and wideband I/Q demodulation without IF transformers or filters. |
| Unit-to-unit consistency | MMIC fabrication ensures <±0.3 dB conversion loss variation across production lots - critical for phased-array calibration. |
| Small ceramic SMT package | 0.126" × 0.126" footprint enables dense RF module integration; compatible with standard reflow profiles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar double-balanced mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC171LP3E | Same die, 3 mm × 3 mm QFN package; requires DC bias on LO port; 0.5 dB higher conversion loss (9.5 dB). | Designed for evaluation boards with bias networks; less suitable for bias-free embedded modules. | Select when board space permits larger QFN and bias infrastructure exists. |
| ADL5801ACPZ-R7 | Active SiGe mixer; 6.5–10.5 GHz RF; +22 dBm IP3 but requires +5 V bias and consumes 120 mA. | Higher integration (LO buffer, IF amplifier); not drop-in due to bias, power, and thermal requirements. | Select when system-level power budget allows active bias and higher linearity is prioritized over simplicity. |
Compared with HMC171C8TR, HMC171LP3E offers identical RF performance in a different package with added bias complexity, while ADL5801ACPZ-R7 trades passive simplicity for higher linearity and active power consumption - making HMC171C8TR optimal for compact, low-power, bias-free microwave front-ends.

FAQ
What is the recommended LO drive level for optimal performance of the HMC171C8TR?
The HMC171C8TR achieves specified conversion loss and isolation at +10 dBm LO drive. Lower drive (e.g., +8 dBm) increases conversion loss by ~1.5 dB; higher drive (+13 dBm) risks degradation without improving linearity. Operation outside ±1 dB of +10 dBm requires re-characterization per application. Always verify LO power at the HMC171C8TR input pad using calibrated measurement.
Does the HMC171C8TR require DC bias for operation?
No, the HMC171C8TR is a passive diode/balun mixer and operates without any DC bias. All ports - RF, LO, and IF - are AC-coupled. This eliminates bias tees, decoupling networks, and associated noise sources, simplifying RF layout and reducing power supply complexity in systems using the HMC171C8TR.
What is the maximum RF input power the HMC171C8TR can handle reliably?
The absolute maximum RF/IF input power for the HMC171C8TR is +13 dBm. For linear operation, the 1 dB compression point is +10 dBm (typ.), meaning signal distortion becomes significant above that level. Sustained operation near +13 dBm may accelerate aging; design margins should keep peak RF input ≤ +8 dBm for long-term reliability with the HMC171C8TR.
How does the HMC171C8TR's LO-to-RF isolation impact transmitter design?
The HMC171C8TR's 32 dB typ. LO-to-RF isolation directly reduces LO leakage into the antenna path during upconversion. This lowers the filter rejection requirement on the transmit chain - for example, relaxing the needed stopband attenuation from 50 dB to ~35 dB - thereby simplifying duplexer or circulator selection and reducing insertion loss in systems built around the HMC171C8TR.
Is the HMC171C8TR pin-compatible with other Hittite mixer variants like HMC171LP3E?
No, the HMC171C8TR (8-lead ceramic SMT) is not pin-compatible with HMC171LP3E (16-lead QFN). Their footprints, lead counts, grounding schemes, and bias requirements differ fundamentally. While both share the same GaAs MMIC core, PCB redesign and layout revision are required to substitute HMC171LP3E for HMC171C8TR - neither is a drop-in replacement.
