Product details
Overview
SKY65720-11 from Skyworks Solutions is a shielded front-end module (FEM) integrating a low-noise amplifier and GPS/GNSS/BDS pre-filter, delivering 16 dB small-signal gain, 1.5 dB noise figure, and >45 dB out-of-band rejection across cellular/WLAN bands at 1.8 V supply. It operates in the 1559–1606 MHz band and is designed for GNSS receiver signal chains in space-constrained portable devices.
For engineers reviewing the SKY65720-11 datasheet, SKY65720-11 pinout, SKY65720-11 application, or SKY65720-11 equivalent, key selection criteria include its MCM package footprint (1.6 × 1.6 × 0.8 mm), integrated 50 Ω input/output matching, LNA enable control, and verified out-of-band rejection performance at 777–5560 MHz.
Technical Context
The SKY65720-11 implements a monolithic front-end architecture with an LNA core and wideband pre-filter co-integrated in a shielded MCM. Its RF_IN to RF_OUT path provides high linearity (IP1dB = –15 dBm, IIP3 = –7 dBm) and reverse isolation of 33 dB, enabling robust operation in noisy RF environments without external filtering.
Control is implemented via a single digital enable pin (VEN), supporting logic-level shutdown with leakage current <1 µA. The device operates exclusively from a 1.8 V DC supply and requires no external biasing components due to internal impedance matching to 50 Ω at both ports.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 1559–1606 MHz - Covers full GPS L1, GLONASS G1, and BDS B1 bands in a single solution. |
| Small Signal Gain | 16 dB typical - Provides sufficient amplification to overcome subsequent stage noise without saturating baseband ADCs. |
| Noise Figure | 1.5 dB typical - Enables high sensitivity GNSS acquisition under weak-signal conditions (e.g., urban canyons, indoors). |
| Out-of-Band Rejection | 45–80 dBc across 777–5560 MHz - Suppresses interference from LTE, PCS, UMTS, WLAN, and 5 GHz Wi-Fi without external SAW filters. |
| Supply Current | 3.8 mA at 1.8 V - Supports ultra-low-power operation essential for battery-powered trackers and wearables. |
| Shutdown Current | 0.1–1 µA - Enables deep power-down during non-tracking intervals to extend system battery life. |
| Input/Output Impedance | Internally matched to 50 Ω - Eliminates need for external matching networks, reducing PCB area and component count. |
Pinout & Package
The SKY65720-11 is housed in a 9-pin Multi-Chip Module (MCM) measuring 1.6 × 1.6 × 0.8 mm, compliant with MSL3 (260 °C reflow) and RoHS requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF_IN | Single-ended 50 Ω RF input port for GNSS antenna signal; internally matched, no external DC blocking required. |
| 2, 4, 5, 6, 8 | GND | Five dedicated ground terminals - ensure low-inductance RF grounding and thermal dissipation in compact layouts. |
| 3 | VEN | LNA enable control input; logic-high (≥VCC – 0.3 V) activates LNA, logic-low (≤0.3 V) places device in shutdown mode. |
| 7 | VCC | 1.8 V DC supply input; bypass capacitor placement adjacent to this pin is critical for RF stability. |
| 9 | RF_OUT | Single-ended 50 Ω RF output port to GNSS receiver IC; maintains gain flatness and return loss >15 dB across band. |
Key Features
| Feature | Design Value |
|---|---|
| Shielded MCM construction | Prevents RF coupling between internal LNA and filter stages, eliminating need for external shielding cans in high-density layouts. |
| Integrated GPS/GNSS/BDS pre-filter | Provides in-band insertion loss <2.5 dB while rejecting cellular/WLAN interferers - replaces discrete SAW + LNA solutions. |
| Single 1.8 V supply operation | Eliminates requirement for dual-rail or adjustable bias supplies, simplifying power architecture in portable GNSS subsystems. |
| Minimal external components | Requires only three external capacitors (input/output DC blocks + VCC bypass) - reduces BOM count and layout complexity. |
| Thermally enhanced ground pad | Five GND pins plus exposed die attach pad enable efficient heat transfer in thermally constrained mobile PCBs. |
Applications
| Smartphones | Fitness Trackers |

Use Value: Extends tracker runtime beyond 7 days per charge by minimizing active and standby current draw without sacrificing sensitivity. |
| Laptop PCs & Tablets | Automotive Telematics |
Use Scenario: Embedded GNSS module in thin-and-light notebooks where antenna placement near display bezels introduces strong out-of-band noise. IC Role / Device Role / Timing Role: High-isolation (33 dB |S12|), high-rejection front-end protecting baseband receiver from display EMI and USB 3.0 harmonics. Use Value: Maintains consistent C/N0 >42 dB-Hz across all operating orientations without requiring mechanical shielding or layout redesign. | Use Scenario: Vehicle-mounted navigation unit operating in harsh RF environments with AM/FM broadcast, LTE, and DSRC transmitters nearby. IC Role / Device Role / Timing Role: Robust GNSS signal conditioner delivering stable gain and NF over –40°C to +85°C case temperature range. Use Value: Ensures reliable cold-start acquisition (<30 s) even when mounted behind metal dashboards or near infotainment antennas. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar GNSS front-end applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QM11136 | 17 dB gain, 1.4 dB NF, but no integrated pre-filter - requires external SAW filter for cellular rejection. | Suitable for designs already using discrete filtering or needing higher gain margin at expense of board area. | Select when system-level filtering strategy favors modular design or when tighter gain tolerance (±0.3 dB) is required. |
| Broadcom AFEM-8060 | 15 dB gain, 1.6 dB NF, includes LTE B2/B4/B5/B12/B13/B25/B41 notch filters - broader cellular coverage but larger 2.0 × 2.0 mm package. | Better suited for global smartphones requiring multi-regional LTE band support beyond GPS-only use cases. | Choose when designing for worldwide carrier certification and need extended out-of-band rejection below 700 MHz. |
Compared with QM11136 and AFEM-8060, the SKY65720-11 offers the smallest footprint (1.6 × 1.6 mm) and highest integration level for GPS/GNSS/BDS-only applications, trading some cellular band coverage for minimal component count and lower system cost.

FAQ
What is the operating frequency range of the SKY65720-11?
The SKY65720-11 operates across 1559–1606 MHz, fully covering GPS L1 (1575.42 MHz), GLONASS G1 (1602 MHz), and BDS B1 (1561.098 MHz) bands. This range is specified under recommended conditions (VCC = 1.8 V, TC = +25°C) and validated per Table 3 of the official datasheet. Performance remains functional across –40°C to +85°C case temperature.
Does the SKY65720-11 require external matching components?
No, the SKY65720-11 features internal 50 Ω impedance matching at both RF_IN and RF_OUT ports. Only three external capacitors are needed: one DC-blocking capacitor at RF_IN, one at RF_OUT, and one VCC bypass capacitor. No inductors, resistors, or additional matching networks are required for nominal operation.
What is the shutdown current consumption of the SKY65720-11?
The SKY65720-11 draws 0.1–1 µA in shutdown mode when VEN = 0 V and no RF signal is present. This ultra-low leakage enables extended battery life in intermittent-tracking applications such as wearable GNSS loggers. The specification is guaranteed per Table 4 of the datasheet under standard test conditions.
Can the SKY65720-11 be used with 2.5 V or 3.3 V supply rails?
No - the SKY65720-11 is rated for 1.8 V nominal supply only, with absolute maximum VCC of 3.1 V. Operation outside 1.8 V ±5% degrades gain flatness, increases noise figure, and may violate the 1.5 dB typical NF specification. Designs requiring higher voltage rails must use a dedicated 1.8 V LDO regulator for the SKY65720-11.
Is there an evaluation board available for the SKY65720-11?
Yes, the SKY65720-11-EVB evaluation board is officially supported by Skyworks and documented in the SKY65720-11 datasheet (Figures 3–4). It provides a complete reference design with optimized RF layout, calibrated measurement points, and solder mask-defined ground vias - enabling rapid characterization of SKY65720-11 gain, NF, and OOB rejection.
