Product details
Overview
HMC340ALP5E from Analog Devices (formerly Hittite Microwave) is a GaAs MMIC double-balanced dual mixer IC operating from 1.7 to 4.5 GHz RF/LO, delivering 8.0 dB typical conversion loss, +20 dBm input IP3, and 45 dB LO/RF isolation. It serves as a passive upconverter/downconverter or I/Q modulator in wireless infrastructure transceivers.
For engineers reviewing the HMC340ALP5E datasheet, HMC340ALP5E pinout, HMC340ALP5E application, or HMC340ALP5E equivalent, key selection criteria include its dual-channel amplitude balance (0.1 dB), DC–1.5 GHz IF bandwidth, RoHS-compliant 5×5 mm QFN package, and suitability for image-reject and SSB architectures requiring high port-to-port isolation.
Technical Context
The HMC340ALP5E integrates two identical GaAs Schottky diode-based double-balanced mixer cells with on-chip baluns, enabling simultaneous independent RF/LO/IF paths per channel. Its symmetry supports external hybrid coupling for image-reject downconversion or single-sideband upconversion without external phase-matching components.
It operates passively with +13 dBm LO drive, exhibits 33 dB LO/IF isolation and 0.25 dB max amplitude balance across temperature (−40°C to +85°C), and maintains stable conversion gain over frequency due to monolithic impedance matching at all ports (50 Ω DC-coupled RF/LO, DC-capable IF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF/LO Frequency Range | 1.7–4.5 GHz - Supports full-band operation in LTE/WiMAX base station front-ends without tuning. |
| IF Bandwidth | DC–1.5 GHz - Enables baseband I/Q modulation and wideband IF sampling without external AC coupling. |
| Conversion Loss | 8.0 dB typ. - Defines signal attenuation in downconversion; impacts receiver noise figure budget directly. |
| Input IP3 | +20 dBm - Determines third-order intermodulation headroom in multi-carrier wireless systems. |
| LO/RF Isolation | 45 dB typ. - Reduces LO leakage into antenna path, easing filter requirements in TDD/FDD transceivers. |
| Amplitude Balance | 0.1 dB typ. - Critical for I/Q modulator accuracy; minimizes EVM degradation in 256-QAM systems. |
| Package | 32-lead 5×5 mm QFN (LP5) - RoHS-compliant, thermally enhanced surface-mount package with exposed paddle for RF grounding. |
Pinout & Package
Package: 32-lead, 5×5 mm, RoHS-compliant QFN (LP5) with exposed thermal paddle. Requires soldering of all ground leads and paddle to PCB RF ground plane per Hittite Application Note land pattern guidance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 19, 22 | RF1, RF2 | DC-coupled 50 Ω RF ports - Support bidirectional use as up/downconverter; require DC blocking only if DC injection prohibited. |
| 12, 29 | IF1, IF2 | DC-coupled IF outputs - Must sink/source ≤4 mA DC current; external series capacitor required for AC-coupled IF paths. |
| 1,2,4,5,7–11,13–18,20,21,23–28,30–32 | N/C | No-connect pins - May be tied to RF ground without performance impact; improves thermal conduction and shielding. |
| Bottom paddle | GND | Thermal and RF ground reference - Must be soldered to solid PCB ground plane using ≥6 thermal vias for optimal RF return and thermal dissipation. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1048LP4E | Wider 0.3–6.0 GHz RF/LO range; higher 9.5 dB conversion loss; same 5×5 mm QFN package. | Better suited for multi-band radios covering sub-1 GHz to 6 GHz; less optimal for narrowband 2–4 GHz systems where HMC340ALP5E's lower loss matters. | Select HMC1048LP4E when band coverage >4.5 GHz is required; retain HMC340ALP5E for lowest-loss 1.7–4.5 GHz operation. |
| ADL5802ACPZ-R7 | Active dual mixer with 17 dB conversion gain; 0.7–2.7 GHz RF range; different 32-lead LFCSP package. | Requires external bias and consumes ~120 mW; enables receiver gain but adds noise and power overhead. | Choose ADL5802ACPZ-R7 only when system-level gain budget demands active mixing; prefer HMC340ALP5E for passive, low-power, low-noise front-end stages. |
Compared with HMC1048LP4E and ADL5802ACPZ-R7, the HMC340ALP5E delivers the lowest conversion loss (8.0 dB) and tightest amplitude balance (0.1 dB) within its 1.7–4.5 GHz band, making it optimal for high-fidelity I/Q and image-reject systems where passive performance and thermal efficiency are prioritized over wideband coverage or gain.

FAQ
What is the maximum LO drive level supported by the HMC340ALP5E?
The HMC340ALP5E supports a maximum LO drive level of +27 dBm, as specified in its Absolute Maximum Ratings. Operation at +13 dBm LO is recommended for optimal conversion loss and IP3 performance. Exceeding +27 dBm risks permanent damage to the GaAs diode junctions. The HMC340ALP5E datasheet confirms this rating applies across the full 1.7–4.5 GHz LO range.
Can the HMC340ALP5E be used for DC-coupled IF operation?
Yes, the HMC340ALP5E supports DC-coupled IF operation on pins 12 (IF2) and 29 (IF1), provided the connected circuit sources or sinks no more than ±4 mA DC current. Exceeding this limit may cause die malfunction or failure. For AC-coupled IF paths, a series capacitor must be selected to pass the required IF bandwidth (DC–1.5 GHz). This behavior is explicitly defined in the Pin Descriptions section of the HMC340ALP5E datasheet.
Does the HMC340ALP5E require external baluns?
No, the HMC340ALP5E does not require external baluns. It integrates on-chip baluns for all RF, LO, and IF ports, enabling direct 50 Ω single-ended interfacing. This eliminates discrete balun components, reduces insertion loss, and improves amplitude and phase tracking between channels. The functional diagram and General Description in the HMC340ALP5E datasheet confirm monolithic balun integration as a core feature.
What is the thermal resistance (RTH) of the HMC340ALP5E package?
The HMC340ALP5E has a thermal resistance (junction-to-package base) of 60.4 °C/W, as stated in its Absolute Maximum Ratings table. This value assumes proper soldering of the exposed paddle and all ground leads to a multilayer PCB ground plane with ≥6 thermal vias. Derating begins above +85°C ambient, with continuous power dissipation limited to 1.07 W at +85°C and reduced linearly beyond that point. This specification is measured and verified for the RoHS-compliant LP5 package used in the HMC340ALP5E.
Is the HMC340ALP5E pin-compatible with the HMC340ALP5?
Yes, the HMC340ALP5E is pin-compatible with the HMC340ALP5. Both share identical 32-lead 5×5 mm QFN (LP5) footprints, pin functions, and electrical specifications. The sole differences are RoHS compliance (HMC340ALP5E uses 100% matte Sn lead finish; HMC340ALP5 uses Sn/Pb) and MSL1 reflow profile (260°C peak vs. 235°C). No PCB layout changes are required when substituting HMC340ALP5E for HMC340ALP5 in existing designs.
