Product details
Overview
AD8343ARUZ-REEL from Analog Devices is a high-performance broadband active mixer IC designed for RF frequency translation in demanding transmit and receive signal chains. It delivers 7 dB typical conversion gain, +16.5 dBm input IP3 at 1900 MHz, −10 dBm LO drive requirement, 14 dB noise figure, and operates from DC to 2.5 GHz across all ports. It is used in cellular base station transceivers where high linearity and wideband operation are critical.
For engineers reviewing the AD8343ARUZ-REEL datasheet, AD8343ARUZ-REEL pinout, AD8343ARUZ-REEL application, or AD8343ARUZ-REEL equivalent, this page provides verified functional context, validated pin-level interface roles, confirmed RF performance metrics across receiver/transmitter configurations, and real-world design implications of its differential open-emitter inputs and open-collector outputs.
Technical Context
The AD8343ARUZ-REEL implements a silicon bipolar double-balanced active mixer core with hard-limited differential LO drive, enabling precise square-wave switching at up to 2.5 GHz. Its PTAT bias cell ensures thermal stability of LO driver and mixer core currents across −40°C to +85°C.
All ports-RF (INPP/INPM), LO (LOIP/LOIM), and IF (OUTP/OUTM)-are fully differential and DC-coupled, supporting both upconversion and downconversion. The open-emitter RF inputs require external DC biasing, while open-collector IF outputs swing ±1 V centered at VPOS and demand external collector bias networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | DC to 2.5 GHz on RF, LO, and IF ports - enables single-part coverage from baseband to microwave bands without band-switching. |
| Conversion Gain | 7 dB typical - eliminates need for post-mixer amplification in many IF chain designs, reducing noise figure impact. |
| Input IP3 | +16.5 dBm at 1900 MHz - supports high-dynamic-range cellular base station receivers handling strong adjacent-channel interferers. |
| LO Drive Level | −10 dBm into 50 Ω differential - reduces external LO amplifier power and complexity versus higher-drive mixers. |
| Noise Figure | 14 dB - defines minimum detectable signal level in receiver applications; consistent with high-gain active mixer architecture. |
| Supply & Power | 5 V @ 50–60 mA quiescent; 20 μA in power-down - enables low-idle-power sleep modes in battery-assisted or burst-mode systems. |
| Interface Type | Differential open-emitter RF inputs, differential open-collector IF outputs - mandates external bias networks but allows flexible AC/DC coupling and impedance transformation. |
Pinout & Package
The AD8343ARUZ-REEL is housed in a 14-lead TSSOP package (4.4 mm × 5.0 mm, 0.65 mm pitch) with exposed pad for thermal enhancement and ground connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 11, 14 (COMM) | Ground reference | Low-impedance analog/digital ground tie points - must be connected to a solid ground plane with minimal inductance for RF stability. |
| 2 (INPP) / 3 (INPM) | Differential RF input | Open-emitter nodes requiring external DC bias (≈1.2 V) and AC coupling - directly interfaces with baluns or differential filters. |
| 4 (DCPL) | LO driver bias decoupling | Internal PTAT bias node - bypass to COMM with 0.1 μF capacitor to suppress LO driver noise injection. |
| 5 (VPOS) | Positive supply | 4.5–5.5 V main supply for LO driver and bias cell - requires local 0.01–0.1 μF ceramic bypass to COMM. |
| 6 (PWDN) | Power-down control | Active-high logic input: < VS − 1.5 V = normal operation; > VS − 0.5 V = 20 μA standby - enables fast (<2.2 μs) system-level power gating. |
| 9 (LOIM) / 10 (LOIP) | Differential LO input | Common-base stage with 50 Ω differential impedance - accepts −10 dBm ac-coupled LO; internally biased at ≈360 mV. |
| 12 (OUTM) / 13 (OUTP) | Differential IF output | Open-collector nodes requiring external pull-up to VPOS - swing ±1 V when biased at VPOS, enabling direct drive into transformer-coupled IF stages. |
Key Features
| Feature | Design Value |
|---|---|
| Broadband DC-to-2.5 GHz operation | Supports multiband infrastructure radios (e.g., LTE Band 1/3/7/40/41) with one mixer, reducing BOM count and layout complexity. |
| High input IP3 (+16.5 dBm) | Enables coexistence with strong out-of-band blockers in dense RF environments such as macrocell base stations without front-end attenuation. |
| Low −10 dBm LO drive | Reduces LO amplifier output power requirements by ≥10 dB versus passive or older active mixers, lowering system power and heat dissipation. |
| Differential open-emitter/open-collector I/O | Permits optimal impedance matching via external networks - avoids fixed internal termination losses and enables tailored harmonic suppression. |
| Integrated PTAT bias and power-down mode | Ensures stable gain/IP3 over temperature and enables rapid (<2.2 μs) transition between full operation and 20 μA standby for energy-efficient time-division systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar active mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC774ALC3 | Wider bandwidth (DC–4 GHz), higher LO drive (0 dBm), GaAs pHEMT process | Better suited for millimeter-wave test equipment; higher power consumption (120 mA) | Select when extending beyond 2.5 GHz or requiring lower noise figure (<11 dB); not drop-in due to different biasing and package. |
| LT5560EDD#TRPBF | Narrower bandwidth (0.1–4 GHz RF, 0.1–1.5 GHz LO), integrated LO buffer, 3.3 V supply | Optimized for portable/wireless infrastructure with simpler supply and fewer external components | Choose for space-constrained designs needing integrated LO drive and lower voltage operation; trade-off is reduced IP3 (12.5 dBm). |

FAQ
What is the recommended LO drive level for AD8343ARUZ-REEL?
The AD8343ARUZ-REEL requires −10 dBm LO drive into its 50 Ω differential LO port (LOIP/LOIM) for optimal conversion gain and IP3 performance. Driving below −12 dBm degrades gain and linearity; exceeding −3 dBm risks distortion and increased current draw. The internal LO driver is optimized for this level, eliminating need for external LO amplification in most designs.
How does the power-down mode affect AD8343ARUZ-REEL performance?
When PWDN is pulled high (>VS − 0.5 V), the AD8343ARUZ-REEL enters standby mode drawing only 20 μA typical. All RF/LO/IF functionality ceases - no conversion gain, no IP3, no noise figure. Recovery time is 500 ns to full specification compliance. This mode is intended for system-level power gating, not dynamic signal path control.
Can AD8343ARUZ-REEL be used for both upconversion and downconversion?
Yes, the AD8343ARUZ-REEL supports bidirectional frequency translation. In downconversion, RF input (e.g., 1900 MHz) mixes with LO (1730 MHz) to produce IF (170 MHz). In upconversion, baseband or IF input (150 MHz) mixes with LO (750 MHz) to generate RF output (900 MHz). Its symmetric differential architecture and broadband response enable both modes without reconfiguration.
What is the role of the DCPL pin on AD8343ARUZ-REEL?
The DCPL pin on AD8343ARUZ-REEL provides access to an internal bias node within the LO driver circuitry. It must be bypassed to COMM with a 0.1 μF capacitor to suppress high-frequency noise coupling from the LO driver into the mixer core - failure to do so increases LO feedthrough and degrades sideband suppression, especially above 1 GHz.
Does AD8343ARUZ-REEL require external bias resistors?
Yes, two 1% precision resistors (R3/R4 = 68.1 Ω per datasheet Figure 72) are required to set the input stage bias current of the AD8343ARUZ-REEL. These define the 5–20 mA per input leg, directly impacting conversion gain, IP3, and power consumption. Omitting or misvaluing them causes significant deviation from specified RF performance.
